we will do what is necessary to prevent iran from getting the world's worst weapons. >> reporter: president obama has had a frosty relationship with prime minister netanyahu, but on this trip both men have been determined to show that they are staunchal lies, maybe even friends. obama joking about meeting netanyahu's sons. >> they are very good-looking young men who clearly got their looks from their mother. >> well, i can say the same of your daughters. >> reporter: after meeting with obama for more than two hours netanyahu affirmed his trust of the president when it comes to iran. >> i'm absolutely convinced that the president is determined to prevent iran from getting nuclear weapons. >> reporter: later today the president returns to jerusalem where he hopes to bring a little campaign magic to the trip with a speech to some 600 israeli college students. the white house sees this as an opportunity to speak directly to the israeli people. urging them to make a new effort to make peace with the palestinians. >> something they very much want to do. >> indeed, robin, we turn to the latest on that massive manhunt under way in colorado. the head of the state's prison systems gunned down on his front doorstep in front of his wife. abc's clayton sandell is in monument, colorado, with the very latest this morning. good morning to you, clayton. >> reporter: good morning, josh. right now hundreds of investigators are stepping up their man hunt trying to find the person who came to this quiet neighborhood to the steps of the house right behind me to commit cold-blooded murder. this morning investigators trying to solve the murder of colorado prison official tom clements have few clues. one a dark-colored car in the neighborhood at the time of the shooting. they also want to find a woman speed-walking in the area who just might have seen the car and its driver. >> we have no suspect at this point and because we have no suspects we can't identify a motive. >> reporter: clements was at home with his wife tuesday night. he went to answer the front door and was suddenly shot in the chest. >> somebody rang the doorbell. the husband answered and was shot. >> reporter: now police want to know if the man who oversaw thousands of prison inmates was possibly targeted for revenge. >> i kind of had it figured out right away sadly because i thought his position would leave him open. >> reporter: a former warden at colorado super max federal prison says it's a career that creates enemies. >> you have 20,000 individuals. anyone could have a reason to hurt mr. clements. >> reporter: clements was murdered coincidentally the same day the governor of colorado signed tough measures for gun reform. >> tom clements dedicated his life to being a public servant, making the world a better place and he is going to be deeply, deeply missed. >> reporter: now with no suspects police and officials here are on edge. they have now stepped up security at the capital and the governor's mansion. josh. >> we'll have updates all morning long. for more we bring in former fbi special agent brad garrett. we heard for investigators the worst sort of case, a crime at this point without motive and without suspects. the murder of a top corrections official obviously very unusual but there's belief it could actually be related to a specific ruling that he made about a case just one week ago. at this point, brad, what are your thoughts here? >> well, i don't know if you can jump to that conclusion. in other words, mr. clements' position as director of the department of corrections could well have -- it may be a job-related homicide like your example, but just as relevant is the personal side of mr. clements. is this something that has to do with another aspect of his life, his family's life and so investigators are stuck, i believe, at this point at looking at this very large circle. did he know the person who arrived at his home that ultimately shot him? was that a prearranged meeting and hopefully the police have figured that out at this point. so there's a lot of moving parts to this case, but it doesn't appear to be clear what component of his life maybe led to his death. >> you mentioned a personal aspect here. the murderer showing up on his doorstep to do what he did. in this case this may be the only thing they have to go on. is there any sense of how to move the case forward? >> well, the advantage you have is because he lives in an area that has some urban aspect to it so the shooter had to get from point a to point b. is he on video someplace? did he get captured by someone's home security system? was he in a 711 before or after the shooting? this is one of the cases that the little bitty details of checking tapes, interviewing store clerks, all of that could lead to the resolution of this case. >> we can only hope progress is made today. brad garrett, we thank you for your time this morning. now let's turn now to paula faris with the other top developing stories on the morning. paula. >> good morning to both of you. sobering news and begin with new information released about that training accident in the nevada desert that took the lives of seven u.s. marines. military officials released the names of the men who died when a mortar shell exploded in its firing tube. the youngest victim just 19 years old. the oldest, 26. all were based at camp lejeune and all but one had already served in afghanistan. the pentagon has now banned the use of certain mortar rounds until it figures out what caused that misfire. and a new warning about the nation's health. despite our attempts to eat healthier and exercise more a government report out this morning shows the obesity rate is rising from 19% in the middle of last decade to a whopping 29% last year. the rate of diabetes nearly doubled in that time. a jury in ohio has recommended a death sentence for the so-called craig's list killer. richard beasley post phony job listings to lure men to meet him and eventually killed three of them. a fourth survived and testified against him. the fbi expanded the search for the bank robber known as the tall man ban indict, wanted for six heists. his real name is chet evans. they hope his height, 6'10", thus the tall man bandit, hopes people to see him. thieves stole $300,000 in cash and jewels after moving into an empty office above a bank and slowly drilling through the floor till they got down into the vault. their high-tem equipment bypassed all of the alarms except for one. police caught them with that cold, hard cash in hand. just for josh we have this headline. the miami heat fought back from a 27-point deficit to beat the cleveland cavaliers extending their winning streak to 24 games. they have nine to go before tying -- >> unbelievable -- >> all-time -- you should have been sleeping instead of watching. too good. >> there's history to be seen. finally imagine being 9 years old and having a dinosaur species named after you. well, daisy morris doesn't have to imagine. a few years back she uncovered a fossil on an england beach and scientists eventually concluded it was an unknown species of flying dinosaur and look at the name they have given it, vectidraco daisymorrisae. she is so passionate. one expert said her bedroom looks like a natural history museum with all the fossils. how about that for show and tell. >> robin? >> that's great. >> okay, you two. now to what could be a major breakthrough in the fight against cancer. we're very excited about this. in a clinical trial patients' own immune cells were altered to fight a deadly form of leukemia. one patient is said to be cancer-free after just eight days of treatment. abc's chief medical editor dr. richard besser is here to tell us more. i know there's a lot of complicated science but can you break it down and explain how it works. >> this is pretty incredible. using a patient's own immune system to fight cancer. take a look at this animation. they had five patients with untreatable cancer. they used a virus to inject genetic material into a patient's own white cells to turn them into cancer fighters. those then went out in the body and destroyed all the cancer cells. these patients, they all went into remission. three of them had bone marrow transplants and are doing great. >> we didn't realize one of the patients, our own david aponte, our sound man, we spent time with him and it's incredible. >> yeah, i spoke with david the other day, and, you know, he credits this with saving his life. last summer he had had lots of chemotherapy. he thought he was in remission and his cancer bounced back. there was nothing left for him to do. he had this treatment. they injected the cells. overwhelming reaction in his body, eight days later not one cancer cell could be found. he has had a bone marrow transplant. he's doing well. you know, he's getting chemo but he's on the road to recovery. >> and past the 100-day mark, the last time we communicated. we're very excited. i remember when you did a similar story with diane on "world news," precious girl emma and so just describe how other cancers and other people can be affected. >> emma was treated and reported in december. she was the first patient with this type of leukemia to have this. she's in total remission, is doing great. but the idea is, you know, depending on what you inject into these cells you could target them to go after all different kinds of cancers. so the theory is maybe you would change them to go after prostate cancer or breast cancer. you know, it's an endless approach. this study was a safety study so they need to go forward, do it in more people and figure out how do you tame the reaction? it's basically creating a battle in someone's body, their own cells against the cancer cells to see who wins. >> at one point could this be in lieu of having a bone marrow transplant? >> i talked to the researchers who did this study and that's what they're thinking. you know, they didn't want to go that way here. this is the first round. it's just looking at safety but the idea is, you know, if this wipes out all of the cancer cells why would you need to move forward and do a bone marrow transplant. emma did not but here for adults with this cancer only 40% survival rate, here this is an idea you might be able to treat and cure people with this disease. >> this is so encouraging, so promising. nice to see you, rich. thanks so much. josh. >> extraordinary news, robin. now to the brave teenager. dramatic and scary home invasion. she was at home on her own when burglars broke in. her terrified call to 911 all caught on tape and abc's linzie janis has the story. >> he's inside the house. >> he's inside? >> yes. >> he's inside the house. >> reporter: you're hearing the terrified voice of 15-year-old doyin oladipupo as thieves ransack her home and roaming through the very closet she was hiding. >> you still hear him upstairs, just yes or no? >> bring the bucket over here. >> okay, don't talk. >> reporter: alone in the house doyin heard the doorbell ring then the alarm of the home security system. >> living room window, open. >> i took off my shoes because i didn't want him to hear me, and i grabbed this phone right here. >> reporter: fearful but clever doyin showed our reporter how she bolted into her parents' walk-in closet crouching underneath a rack of clothes. seconds later the intruders enter the room. >> bring the bucket over here. >> i can hear him. don't talk. >> i was so scared. i could see them and i thought they were going to see me. >> reporter: the dispatcher had the high school student remain on the line tapping on the phone to answer questions. >> my officers want you to know your whole house is surrounded. >> reporter: minutes later the burglars exit the house but the three teens are apprehended by police in the driveway. >> after the victim identifies property in the vehicle as belonging to her, the three were arrested. >> reporter: her relieved mom says she's simply in awe of her brave daughter. >> my daughter's strong. i didn't even know how strong she was until the police told me what happened. she's got an inner strength, you know, and it showed yesterday. >> reporter: for "good morning america," linzie janis, abc news, new york. >> bravery, i think we all hope we have in that moment. >> yeah. >> remarkable stuff. >> okay. how big a buzz are you getting from your morning coffee? >> pretty big. >> probably not as much as you might get from the java being billed as the world's strongest, called death wish coffee and has twice the caffeine. gio benitez is here with the buzz. i have to say it smells great. >> you can feel it. >> what about that name death wish coffee. >> yeah. >> well, this morning the maker of death wish coffee says it's so powerful you'll only need one cup a day. but people all over are asking is it safe to drink that much caffeine? if regular coffee doesn't pack enough of a punch, would you drink this, coffee beans packaged with a skull and cross bones. the name, death wish. >> when it comes right down to it it's just a very strong cup of coffee. >> reporter: that's mike brown, the founder and owner of what he calls the strongest cup of coffee in the world. he uses beans that give you twice the jolt, doubling the caffeine in your average cup. that's where he got the fame death wish. >> we're making the world's strongest coffee. can't call it puppies or kittens or anything like that. >> reporter: lots are talking about caffeine these days. monster energy drinks will soon begin listing caffeine content on its cans. here's how much caffeine we're talking about. right now a 16-ounce monster energy can has about 160 milligrams of caffeine. 16 ounces of starbucks coffee, about 330 milligrams. but the same amount of death wish coffee, about 660 milligrams of caffeine. >> for someone who drinks coffee all the time i don't think they'll notice much of a difference but if you're someone who doesn't drink coffee at all this could be a shock to the system. >> reporter: at his coffee shop in upstate new york, brown only sells the beans. he doesn't brew death wish coffee there, not yet and when i asked if he drinks this super coffee -- >> yeah, i drink it only on the mornings when i need to get a lot of stuff done and dragging. no, i can't handle it every morning. >> reporter: well, certainly tastes friendly and while dr. besser says it's like having two cups of coffee at once, if you're the kind of person that has ten cups a day, imagine how much caffeine you're getting into your system if you're drinking some of this stuff, we have it here and you can see the logo. sam is enjoying it. >> i love it. i think it's fantastic. >> i recommend everyone stay tuned to this broadcast. >> how much does it cost? >> about 20 bucks a pound. >> oh. >> for me i will -- you're a connoisseur. >> to me it's a very smooth cup of coffee. now, check with me in about 15 minutes and see if i'm in the corner hugging myself. >> suddenly we're all jitery. >> exactly. >> we'll check back with you. >> tastes good. in the meantime, ladies and gentlemen, spring wants you to know it's sorry. spring wants you to know there was traffic on the expressway, that the planes were running late, that its cat got out of the house just before it was supposed to be here. spring is not showing up for at least a week in a lot of the country and as a matter of fact as cold as it was yesterday colder in some places today. 6 in detroit. these are the windchills, by the way, 21 below in devil's lake. cincinnati at 12, that cold air is spreading west as well into the deep southeast. oklahoma city by saturday, you're at 49 degrees. dallas, 58 degrees by the time we get to sunday. albuquerque, 50 degrees, as well. so that cold air settles into a good part of country for a few days and talk more about that in the next half-hour. we'll talk more about that. >> it's a pound, pound, pound to the heart, yes, no, it's working. rrrrr! we'll have more weather in the next half hour, i think. >> and then some. >> and then some. >> weather in ten seconds. >> still to come on "good morning america," more testimony about jodi arias' state of mind, torn apart in court. why her psychologist was forced to admit she lied to him. more massive jackpots than ever before. are your chances of winning the lottery finally getting better?
