Country this year. This marks a 56 increase over 2015. Five officers were killed in the ambush attack in dallas. Three more were killed in a similar attack in baton rouge, louisiana just ten days later. In total, 21 Law Enforcement officers were killed in ambushstyle attacks across the country. Frederick frazier is the head of the Dallas Police association and says there are simple solutions. You have to have more ficers on the street. Thats the easiest answer because an officer needs a partner. He needs somebody to watch his side, watch his back. Reporter for heidi and her two girls the grief has been unbearable. Back in july 10yearold caroke down when she told us about the last time she saw her dad put on his uniform. He was leaving to go to work, and i was leaving to go to a movie. And he said to me, what if this is the last time you ever kiss me or hug me . Reporter did he always say that . No. That was probably the first time he ever said that. Reporter was this kiss any different . Yes, it was. Reporter how . It just felt different to me. I felt something bad was going to happen. Reporter texas and california had the most officer fatalities this year. Reena, the deadliest calls for officers to answer are domestic disturbances. Omar villafranca, thank you. In syria a new ceasefire has taken effect. Earlier truces have not held for long. This one was brokered by russia and turkey, who are on different sides in the syrian civil war, which is nearly six years old. Holly Williams Joins us from istanbul. Holly, what do we know . Reporter well, reena, the Syrian Regime has apparently agreed to this deal, along with one of the main Syrian Opposition alliances. And the idea is that if it holds this could lead to peace talks in january. But there are dozens of Syrian Opposition or rebel groups, and weve spoken to some groups this evening who say that they did not agree to this ceasefire. Remember also that this ceasefire deal only includes the Syrian Regime and some Syrian Opposition groups. This deal does not include isis or a powerful kurdish group. So while this could be a turning point, it certainly isnt an end to the syrian civil war. How is the u. S. Reacting to this deal, holly . Reporter well, reena, the u. S. Has called this a positive development, but this deal has effectively sidelined america in syria. Russias lethal air campaign in syria has managed to prop up the Syrian Regime, and its helped moscow look like a truly global player, really for the First Time Since the end of the cold war. Now perhaps this will allow russias president , Vladimir Putin, to portray himself as a peacemaker. And russia has brokered this ceasefire deal not with washington but with turkey, an american nato ally that is growing ever closer to moscow. Holly williams in istanbul. Thank you, holly. Today tributes to Debbie Reynolds filled social media. The actress died yesterday at 84. There were drawings, many depicting reynolds with her daughter carrie fisher, who died one day earlier. Some showed reynolds in the rain gear that she wore in singin in the rain. And fisher shown as star wars Princess Leia. Last night fans raised light sabers in honor of fisher at impromptu vigils all over the country. Some dressed as star wars character. Reynolds son todd fisher said the actress went to be with carrie. Well, coming up next, can you really die of a broken heart . Dr. Jon lapook examines that. And later, were on the hunt for thieves stealing something more valuable than gold.

Com there is no official word on what caused Debbie Reynolds death, but many believe it was no coincidence that she died just one day after the death of her daughter, carrie fisher. Medical experts say broken heart syndrome is real. More now from dr. Jon lapook. Reporter its unclear what led to Debbie Reynolds death just one day after her daughters, but emotionally stressful events like the death of a spouse or child can trigger a sudden surge in stress hormones that are felt to stun the heart and prevent it from pumping properly or cause an artery supplying the heart to go into spasm. This entire part of the heart is not moving at all. Reporter cardiologist dr. Harmony reynolds of Nyu Langone Medical Center has studied this underrecognized condition which occurs mainly in older women, many of whom have no obvious preexisting heart disease. This is a heart attack syndrome that unlike typical heart attack occurs with the arteries completely open. And the area of the heart thats affected is quite large, but if people survive the event it all goes away. Reporter symptoms can resemble a heart attack, including chest pain and shortness of breath, but may be subtle, causing women to delay seeking help. We dont necessarily understand why an emotional connection exists, but we know that the brain and the heart are closely connected. You can die of heartbreak. But exactly how that happens and exactly why, we dont know. Reporter most people fully recover, but death can occur from problems like Heart Failure or an irregular heartbeat. In addition, a blood clot in the heart can travel to the brain, causing a stroke. Any idea how common this is . Its probably relatively uncommon but nobody knows exactly how common it is because its probably been flying under the radar for years. But now doctors are getting increasingly better at recognizing it. In 2012 about 6,200 cases were diagnosed in the united states. That represents a 20fold increase from just six years before that. Incredible the impact of stress hormones on the body. Thank you, dr. Jon lapook.

Well, coming up, were on the chase for crooks stealing hot wheels of cheese. ,,,,,, finally tonight, thieves are always after the cheddar. Except in italy, where theyre stealing a close cousin. Heres seth doane. Reporter 9 30 p. M. , eight officers keep watch from a convoy of three police cars. These patrols happen every night . Every night, yeah. Reporter in 30 years on the force Alessandro Vaccari has never seen a wave of robberies like this. Police blame organized crime. No surprise there. But the target . This cheese can be quite valuable. Yeah. Reporter yes, cheese. These are the streets of reggio emilia, italy, home to parmesan. There have been so many thefts, vaccari explained. Cheese is a bit like gold here. The price is so high. Exhibit a, a single wheel of cheese can sell for over 500. The staple of spaghetti dinners everywhere is the economic backbone of these small italian towns. Parmesan is so valuable that it is used as collateral for loans. Believe it or not, this is a bank. Its a vault filled with more than 120 million worth of cheese. To be certified Parmigiano Reggiano it must age for at least a year. So that means cheese, a whole lot of it, is stacked up in warehouses on small, rural unprotected farms. Lorenzo pinetti showed us how thieves made off with 100,000 of his cheese in minutes. Theyd make an Assembly Line and steal this piece and then this piece. Italys Parmesan Consortium figures about 7 million worth has been stolen in the last two years. Theres a robust black market. So steppedup patrols and new Security Systems are now in place. But surely this will not be the last time thieves come to visit us, pinnetti said. Small independent farmers are what makes this cheese so good and such a delicious target. Seth doane, cbs news, reggio emilia, italy. Thats the overnight news for this friday. For some of you the news continues. For others check back with us a little later for the morning news and cbs this morning. From the Broadcast Center in new york city, im reena ninan. Announcer this is the cbs overnight news. Welcome to the overnight news. Im tony do kooupll. As he promised, president obama unveiled a boatload of sanctions against russia for its efforts to influence the recent president ial election. Nearly three dozen Russian Diplomats have been given three days to get out of the country. And that is just the start of it. Chip reid reports. Russia was engaging in malicious cyber activity intended to interfere with our election. Reporter and for that white house spokesman eric schultz says russia must pay a price. U. S. Intelligence agencies say the russians were engaged in an effort to harm Hillary Clintons campaign, thereby helping the campaign of president elect donald trump. The administrations retaliatory actions mean the 35 government officials from the Russian Embassy in d. C. And the russian consulate in San Francisco have to leave the country within 72 hours. Schultz says they cannot hide. Well, all their credentials will be revoked. So they wont be able to theyll have no protections here. Theyll have no diplomatic immunity here. They will be persona non grata. So they will have to leave the country. Reporter in addition, two russian compounds believed to have been involved, one in new york and one on the Eastern Shore of maryland, will be closed. Further, two russian intelligence agencies are being identified and sanctioned for their role in the hacking, along with three companies and four individuals who allegedly assisted. And two russians have been identified as cyber criminals. The Administration Says one of the men has stolen more than 100 million from u. S. Businesses. The white house says additional covert actions against the russians will not be announced because they are highly classified. On capitol hill members of both parties have come out in support of the president s actions. Republican speaker of the house paul ryan called them overdue, and republican senators john mccain and Lindsey Graham say they intend to lead the effort in the new congress to impose stronger sanctions on russia. A russian dpsh spoekdsman for russian president Vladimir Putin says there will be appropriate retaliation. As for president elect trump, he released a statement saying, its time for our country to move on to bigger and better things. But he added that he will meet with leaders of the Intelligence Community next week to be updated on the facts of this situation. President elect donald trump has dismissed the hacking charges against russia, calling them ridiculous. Mr. Trumps aides want u. S. Intelligence agencies to prove that moscow was behind the hacking and how it was done. Jeff pegues has a look at some of the evidence that has russian fingerprints all over it. Reporter u. S. Intelligence services dont often release the details of their analysis, but today they did as part of an ongoing effort to pull back the curtain on what u. S. Officials believe is malicious russian cyberactivity codenamed grizzly st steppe. Investigators believe the initial cyberattack of Democratic Party officials began in the summer of 2015 when the first hacking unit dupd apt29 sent out a barrage of emails containing a Malicious Link to over 1,000 recipients including multiple u. S. Government victims. Once someone clicked on the link, the hackers were in the system. According to the document, the hackers successfully compromised the u. S. Political party and stole email from several accounts. About a year later in the spring of 2016 another hacking unit called apt28 also targeted Democratic Party officials and once again deployed malicious emails that tricked recipients into changing their passwords. According to u. S. Intelligence officials, that hack likely gave russian operatives access to the information of senior Democratic Party officials, which was then leaked to the press and publicly disclosed. Russia has denied the all gaigss, but a u. S. Official says, i would never expect russia to come out with their hands up and acknowledge what they did. While the public largely became aware of the cyberattacks during the Democratic National convention, u. S. Officials believe that for about a decade Russian Intelligence Services have been conducting Cyber Espionage on a wide range of targets here in the u. S. U. S. Officials say that they have no reason to believe the russian cyberattacks will stop. Reena, the other problem is it is likely the russian hacking units hit targets that have yet to show up on u. S. Investigators radar. Funeral arrangements are still being made for singer and actress Debbie Reynolds who suffered a stroke just days after the death of her daughter carrie fisher. The pair were inseparable in recent years and even lived next door to one another. Now they could be laid to rest together. Brendan fraser reports.

Actor Denzel Washington was already on top of the world when he decided to take on a monumental project, to bring to the screen the works of one of americas greatest playwrights, the late August Wilson. Wilson wrote ten plays chronicling the africanamerican experience. Washington will produce all of them. The first one, fences, opened on christmas day. Bill whitaker reports for 60 minutes. I understand that you made it clear to everybody on the set that youre not after good, youre after great, and that anybody whos coming to work on this film where did you hear that . Has to want great. Theres nothing wrong with that. Nothing wrong with it. Well, the best you can be. You ought to stop that lying. Reporter fences is set in pittsburgh in the 1950s and 60s, when racial integration was just gaining a toe hold. He said nothing, told me to go down to the Commissioners Office next friday. Whoa. Reporter washington plays 53yearold troy maxon, whose life is defined by his Big Personality and his bigger disappointments. Because i asked a question . Thats all i did. Great ability to play baseball but he came along at a time blacks werent accepted yet in the big leagues. So he was frustrated by that. Anybody can drive a truck. How come you got all the whites driving and the colored lifting . Reporter washington filmed fences in the hill district of pittsburgh, a once vibrant black neighborhood where August Wilson grew up. The people who went to work and to church and raised their families here inspired many of his plays. Its a pittsburgh story, and i wanted it to be in pittsburgh. The stories i get from people, all of that helps to feed the film. Reporter washington turned this vacant hill district house into the maxon family home. Familiar to many of us who grew up in a black workingclass neighborhood at the time. I swear i know this house. Yeah, man. Now, okay. Now you tell me. My aunt lived in this house. Yeah . The front room and uhhuh. The parlor. The parlor. Ill take you for the tour. This is the dining room. And this youve got jesus, Martin Luther king in the 60s this was in every africanamerican house. You know i had to put that in there. You know it. Every africanamerican house. And they ought to be felt. You know, that whatever that felt stuff. Of course, youve got jesus, Martin Luther king and john f. Kennedy. And her baby. You notice she dont have no pictures of troy up there. Thats terrible, actually. This is the back yard. The action takes place right out here. What are yall out here getting into . What you worried about what were getting into for, woman . Reporter fences is the story of a family unraveling. Troy from his wife rose and from his son corey. Look, boy, the white man aint going to let you get nowhere with no football no way. Now, you get your book learning so you can work your way up at the a p and learn how to fix cars or build houses, get you a trade. This way you got something cant nobody take away from you. Do you see your father in troy . In some regards. He couldnt read well. He had the same conversation with me about getting a good trade. You know, he worked for the Water Department in new york. And he could get me on at the Water Department. He said i could be a supervisor in 25 years. Hes like, you get a good job get a secure job. Yeah, a secure job. Exactly. And like rose, my mother could see further. No, hes got to get an education, hes got to go to college and you know, he couldnt see that far. Times have changed, troy. People change. The world changing and you cant even see it. Huh. Woman, i do the best i can do. I come in here every friday, i carry a sack of potatoes and a bucket of lard. You line up at the door with your hands out. I give you the lint from my pockets. I give you my sweat and my blood. I aint got no tears. I done spent them. We go upstairs in that room at night, i fall down on you and try to blast a hole into forever.

I remember seeing my father in the driveway listening to the ball game. Yes, i remember the door would be open. Hed have his foot out. And hes just listening to the ball game. And i realize as when i got older it was the only place where he had a chance to he just dealt with one boss, now hes about to go in the house and my mothers in there, the other boss, and he had maybe ten minutes to himself to be the boss. In the driveway. In the driveway. Listening to the ball game. Listening to the ball game. And because he had to come home and eat and then go to the night job. Do you tap into that to bring that out into the performance . Its in there. Its got to be. Yeah, its got to be. Jesus reporter viola davis told us she admired Denzel Washington long before they acted in fences together on broadway. When i was younger, i just thought he was goodlooking. You know, denzel is so goodlooking. Was it difficult having him as both leading man and director . Not at all. I thought he flowed in and out of those two things effortlessly. He never gets in the way. I think thats a testament to him as an artist. That his ego took a back seat to anything. I think this is a role of a lifetime for her. And she bites down and she tears it up. Its not easy for me to admit that ive been standing in the same place for 18 years. Well, ive been standing with you ive been right here with you, troy ive got a life too. I did 18 years of my life to stand in the same spot as you. Dont you think ive ever wanted other things . Dont you think i had dreams and hopes . What about my life . What about me . People say everything in film is small, every moment is small, youve got to play it small. And sometimes moments are not small. Its painful to watch. Well, it should be. Because thats just how august wrote. He didnt write small. Reporter August Wilsons themes are big and universal. His plays chronicle the struggles of black americans searching for what everyone wants. Dignity, love, security. Across generations and in the face of overwhelming odds. His genius was capturing the sensibilities, the unique cadences of africanamerican life, with finely crafted language. Theres a line that says what that mean to me bonnie working . . What that mean to me beenie working . Go ask her for 10 if shes working. Talk about bonnie working. Why aint you working . So theres a rhythm theres a rhythm to it. Not what does that mean to me . He wrote what that mean to me. What that mean to me bonnie working. I dont care if shes working. Go ask her for 10 if bonnie working. Talk about bonnie working. Why aint you working . Like shakespeare. The punchline is actually set up if you just play the music. Reporter at a scoring session we found washington putting music to wilsons words. Its all part of being the director, which hes done twice before. So we can just pick it up at 37. I just dig the process. Days like this it dont get no better than this. And in theory im the boss. Dont tell nobody. Like really . August wilson wanted to have a black director to make the films. He got his wish. He got his wish. Yeah. No pressure on me because the last i checked i was black. I am black. Check. Yeah. I covered that. I didnt have to audition. He said he didnt think a white director would be able to do it justice. I think its a cultural thing more than a race thing. And culturally you understand no question. You understand this place and these people. No question. When we would come out and pour a little for the boys upstate, i grew up with that. We always poured out a little liquor for the guys that were locked up or the guys that were dead. I know what it smells like when my sisters getting her hair fried with a hot iron on sunday morning.

Federal price supports for the dairy Industry Cost the u. S. Taxpayer more than a billion dollars a year. Now the milk industry and its friends in Congress Want more. Theyre calling on the fda to limit which products can actually be called milk. People who enjoy soy milk and almond milk say thats ridiculous. Errol barnett has our story. Well, weve all heard the expression dont cry over spilled milk, right . But right now there are tears of frustration in the debate over who gets to put milk on their labels. On one side you have the long dominant dare farmers. And on the other you have the new kids on the block. Strong is good. Rock it tennis star venus williams. I do plants. Reporter and hiphop producer d. J. Khaled appear in these new uptempo ads for silk almond and soy milk. Theyre part of an industry of plantbased products described as milk substitutes. They generated 1. 4 billion this year and grew 54 over the last five years in the u. S. Real milk has eight times more protein than almond milk. Reporter milk producers are facing decline, dropping 11 in sales over the last year. Now theyre fighting back. We have seen a dropoff in consumption of dairy products, and also we have seen a significant price drop. Reporter patty leonards family has been farming in Northern Virginia for almost a century. She milks her cows twice daily and says nondairy milk products are successful because theyre misleading. They are using the good name and the good qualities and the standard of milk to share their product. What makes it all the more important that we have a clear definition and a clear standard so that our consumers have a clear understanding of what theyre purchasing and theres no confusion. Reporter 32 congressmen from dairyproducing states agree, penning this letter urging the fda to enforce its existing definition of milk, which states, it is obtained by the complete milking of one or more cows. But how much confusion is there between cow milk and its substitutes . I dont think theyre the same as milk, and i think that confuses people. I think it should continue to be called milk. Its used like milk. Worldwide, this is the same terminology that has been used for years. Reporter for Nancy Chapman of the Soy Foods Association the hope is the fda widens its definition. When you drink soy milk, it is equal in terms of its ability to support growth and development as is a dairy cows milk. Reporter chris galen works for the milk producers federation. Would you be all right with a looser definition . Ive never milked a soy bean. I dont suppose if you cracked one open youd find much milk or any liquid there. All we want is for the government to do its job and to enforce the regulations on the books that says you dont got mill fk it comes fr milk if it comes from a nut or a seed. Reporter whats interesting is the fda has historically kept out of the debate over who gets to use the term milk. But this time it says it will respond directly to the congressmen who wrote to them. We also reached out to the almond industry for comment and they tell us their product is fortified with vitamins and calcium and that ultimately its up to the consumer to decide. The cbs overnight news will be right back. School science fairs can be a traumatic time for students. The kids dont know what to make, and a lot of times their parents are of little help. Chip reid has one young friend whos a champion at the science fair, and he checked back in with her to see the least inventions. To do the fish reporter when we first met Olivia Mcconnell two years ago she was leading a campaign to make the woolly mammoth the South Carolina state fossil. Olivia mcconnell. Is [ applause ] reporter now 11, shes still making headlines. She and friends riley simms and emily palmer have won first place in seven science fairs in a row. Remember, you cannot touch the disks. Reporter olivia insists theyre a team, but its pretty clear whos in charge. This prizewinning experiment begins with the girls swabbing e. Coli onto petri dishes. Then they soak small pieces of paper in a solution of tobacco, place the paper on the e. Coli, put it in an oven, and wait 24 hours to see if the tobacco kills the e. Coli. So you think that this could actually be a cure for e. Coli . It possibly could. I hope it can. It sounds like theres a nobel prize for science in this. Youre thinking what im thinking. Shes a pretty remarkable young lady. Reporter ann jack, a university of kentucky tobacco researcher, says olivia has all the makings of a great scientist. She has the ability to persevere with something and get it right. Reporter persevere just might be an understatement. Whose house is that . Mine. Reporter last year a massive flood destroyed her familys home and all the tobacco she had so carefully prepared. Did you think that your experiment was over . I never think that. You never do. Never. I dont like to think i cant do this. Because everything is possible. Where did you get that attitude . Probably from my grandma and my mom. I inherited it from the girls in my family. Reporter earlier this year olivia and her team, believe it or not, came in second at a science fair. They say a little adversity builds character. But its hard to imagine she needs any more of that. Ive been told that. Reporter chip reid, cbs news, lake city, South Carolina. Oh, my gosh. Lord have mercy. And thats the overnight news for this friday. For some of you the news continues.
