Finally, david phung jumps in, pulling her out by her arm. Get my dog get my dog her dog. Reporter seconds later, fishing her dog out too. Homes, cars, and routes to safety all under water. All day we have been seeing boat after boat filled with evacuees, and these rescues have been made not be Emergency Responders but by neighbors helping neighbors. Many stranded in their cars on interstate 12, some for over 24 hours without food or water. Day two, theyre trying to evacuate the sick and elderly. As you can see behind me, a lot of the interstate is actually flooded. Weve been here for about 30 hours now. Reporter and more forced to abandon their homes, taking no chances with possibility of rising waters. Where are you going to go from here . Where ill go from here . Just like i did for katrina.

Next to rio where ryan lochte and three other team usa swimmers were robbed at gun point. Recounting a flightening scene. Suspects flashing Police Badges before ordering them to the ground. When lochte refused the situation, it took a more dangerous turn. Matt gutman on rios darker side. Reporter tonight, organizers are scrambling after lochte and his teammates were held up at gun point earlier in morning. Ryan lochte was in a taxi with teammates after an evening out and was stopped by a man in police uniform. He told nbc news he pulled out a gun, he tapped it. And put it to my forehead. I put my hands up, said, whatever. Reporter they had been apparently partying at a friends house and at this clus. And confusion, with the ioc stating that lochte had not been held up at gun point. They spoke and said it wasnt true. Reporter later, they said the incident did happen. That makes up for the latest for the organizers who guaranteed the safety of athletes. To make rio the safest city in the world during the games. Reporter incidents occurring almost daily here. A belgium judo player attacked. Equestrian venue was twice hit with bullets. Last week, we joined the s. W. A. T. Team to see the city without the tourist attractions. Everybody wears this going out . Everybody has to. They have to.

Reporter and this is how it is every time you leave this gate . Yeah, yeah. Reporter we have learned the u. S. State department is assisting in the investigation. And the security situation unlikely to improve, they are reiterating the security to remind them its probably not a good idea to take a local taxi at 4 00 in the morning here. Tom . Not a good idea is right. Thank you. We have more on the games later. Next to milwaukee. The National Guard called in after simmering tensions between police and residents boiled over. Take a look at this. Police cars set on fire. Protesters hurling rocks at officers and one on of them opening fire after police shot and killed a 23yearold black man they say was armed. Tonight, police are revealing details about the threat the officers are facing. Eva pilgrim tonight. Reporter cars are turned over.

A gas station, an auto parts store, and a bank, six businesses in all torched. The suspect, now being identified as sylville smith, was armed, according to authorities, he set off on foot after being stopped. An officer ordered him to drop his weapon, and when he didnt comply, fired several rounds, killing smith. The officer was wearing a body camera. He had a gun in his hand.

Im running against the crooked media. Thats what im running against. Reporter trump blaming the press for his tumbling poll numbers, tweeting if the disgusting and corrupt media covered me honestly and didnt put false meaning into the words i say, i would be beating hillary by 20 . And hes ripping into the New York Times after it published this blistering report about turmoil in his campaign. The newspaper is going to hell. Maybe well start thinking about taking their press credentials away from them. Reporter tonight, the trump camp is doing damage control, running mate mike pence reaching out to Top Republicans like john mccain and jeb bush, hoping to calm party nerves. But many republicans worry hes already headed for defeat. Even trump is raising the possibility. Can you imagine how badly ill feel if i spent all of that money, all of this energy, all of this time, and lost . Reporter in a bizarre move, trump promising a cancer patient that i had will always tell him the truth and admitting to other voters i might lie to you like hillary does all the time. But i will never lie to jackamo. All right, you hold me to it. Reporter tom, trump will get back to the issues tomorrow. Delivering a detailed speech in ohio on his plan to tackle terrorism.

Reporter the google account executive and avid runner found murdered and badly burned last sunday, just hours after taking an afternoon jog in princeton, massachusetts, half a mile from her mothers home. Authorities saying marcotte put up a fight. We believe that there was a struggle that may have resulted in her killer receiving injuries.

Thats a lot of pressure when people expect you to win gold and then you did it. Did you know you were gonna do it . We were confident. Yes, we were very confident once we went out there.

An oklahoma woman had to jump on a plane and race back to her neighborhood to find her house had been taken over. Here is abcs lauren lyster.

It looked like i was in some kind of homeless shelter with mattresses everywhere. Reporter alleged squatters moving into crystal taylors oklahoma house, all while she and her fiance are on vacation in cabo. Crystal rushing home when neighbors alerted her. They broke into my home, they crawled underneath the garage door, they have vandalized the home, and nothing is being done. It should be breaking and entering. Reporter police responding, but the alleged squatters providing a lease, claiming they were the victims of a craigslist scam. I know it reeks. It looks bad on us. When we go another place, we will research the house before we even move in. Reporter authorities still investigating but making no arrests. Once the police are called, they dont have the ability to make decisions on who is right or wrong. Reporter experts say the best strategy here is prevention make the house look occupied, have neighbors check on your home if you cant, and set up a google alert with your property address so you know if anyone is listing it online. And have a copy of documents available that prove you are the homeowner. Experts say this encourages police to treat squatters as trespassers. Tom. Thank you.
