Thats all i can do. And the road to 9 11. A Port Authority detective on a team charged with hunting down the terrorists who would go on to mastermind the 9 11 attacks. I live with a lot of guilt. I could get it done. Now returning to the site of the buildings he vowed to protect. But first here, the nightline 5. And number 1 is coming up in and number 1 is coming up in just 60 seconds. Food. Water. Internet. We need it to live. But what we dont need are surprises, like extra monthly fees. I see you, fee, played by legendary actress anjelica huston. You got me, mark. We just want fast internet for one, simple rate. For all the streaming and the shopping and the newsing, but most of all. For the this. Internet for one everyday simple price and no extra monthly fees. Good evening and thank you for joining us tonight. An unexpected killing with a bewildering claim. A once aspiring pastor calls 911 reporting that he woke from a dream and found his wife dead. He says he remembers nothing, pointing to a large dose of Cold Medicine he took. Now legal experts are weighing in, could his bizarre story actually hold up in court . They looked like the picture of marital bliss. Lauren and matt phelps, newlyweds, married for barely ten months. Lauren, 29, a sunday School Teacher and auditor who ran an Online Business on the side. So thank you guys so much for watching, and i will talk to you guys later. Bye. Reporter matt, 28, worked at a lawn service in North Carolina and once attended a bible college. But that image of what seemed from the outside like the perfect allamerican couple shattered as caught in a dramatic call to 911. Where is the knife right now . Reporter matt phelps now stands accused of murdering his wife. He hasnt yet entered a plea, and what we dont know is whether or not cold medication he took will play a role in this case. Sir, you could receive the Death Penalty or life without the possibility of parole. Reporter just after 1 00 a. M. On friday a man called authorities with this startling revelation. I had a dream, and then i turned on the lights and shes dead on the floor. How . How . I have blood all over me, and theres a bloody knife on the bed. And i think i did it. Reporter the Raleigh PoliceDepartment Says it has altered the recording to disguise the callers voice. The man said he took overthecounter medication to help him sleep just hours before. I took more medicine than i should have. What medicine did you take . I took i took coricidin cough and cold because i know it can make you feel good. So a lot of times i cant sleep at night. Is she breathing at all . Is her chest moving . Is anything going on with her . No. Okay. Were going to the blood is dried on me. Its dried . The blood is not wet on me. The blood is dry. When officers arrived at the phelps home in raleigh, they found lauren with stab wounds. They rushed her to the hospital, where she was pronounced dead. Laurens heartbroken family said in a statement, she was all about her family. Her four nephews were her whole world and church was a priority for her. Matt phelps defense attorney is asking the public to wait for more information before judging his client. Be patient with everybody so that we can all together get to the bottom of this really significant tragedy. Reporter bayer, the manufacturer of coricidin, defended its product in a statement, saying Patient Safety is our top priority and we continually monitor adverse events regarding all of our products. There is no evidence to suggest that coricidin is associated with violent behavior. What phelps said in that 911 call already raising questions. Listen, this aint the cold and flu season. Okay . So theres no evidence he had the cold or a flu. He also said he takes coricidin because it makes him feel good and helps him go to sleep. He said nothing about being ill. If there was literature, proof, evidence that this particular cough syrup has led to violent episodes in the past, could there be a defense . Maybe. Particularly if there was no warning. But there is no evidence that we know of. Ambiens a different story. Reporter one of the bestknown cases of whats become known as the ambien defense is that of carrie kennedy. I have no memory. Until i was stopped at a traffic light. Reporter in 2012 kennedy, the daughter of robert kennedy,d allegedly left the scene. Police found her slumped over the wheel of her car. She faced a single misdemeanor count of driving while impaired. Her defense argued that she unnothingly took a generic form of ambien, mistaking it for her thyroid drug, and one of the expert witnesses in the trial, dr. David benjamin, said the medication can cause an automatic type of behavior or zombieism and that people might become impaired but not know it. Had she had her faculties about her she would have pulled over and called aa. Reporter sanofi, the maker of ambien, said in a statement that it stands behind the robust Clinical Data that have demonstrated the safety and efficacy of ambien since its approval in the u. S. In 1992. Kennedy was found not guilty. But in another case, one not involving a traditional pharmaceutical, the outcome was tragically different. Report of a Domestic Violence in prort. Reporter in april 2014 Christine Kirk called 911 saying her husband had taken some marijuana and was talking like it was the end of the world and wanted her to shoot him. Telling the 911 operator that he was totally hallucinating. He grabbed the gun and shes screaming. The line disconnected. Reporter richard kirk was charged with firstdegree murder of his wife and he pled not guilty by reason of insanity. Researchers suggesting the potlaced candy which is legal in colorado may have contributed to his psychotic break. The guardians of kirks children filed a wrongful death suit against the maker and distributor of the chewy candy alleging they negligently, recklessly and purposefully concealed vital dosage and labeling information claiming the package doesnt warn buyers that the high in edibles could lead to paranoia, psychosis and hallucinatio hallucinations. We dont have a lot of literature on what the side effects would be on a person who has ingested recreational marijuana. So a manufacturer could potentially be held liable for that. An attorney for the makers of the candy told abc that they were complying with all state labeling requirements at the time that said marijuana could have Adverse Health effects and called the suits claims preposterous and baseless. Kirk later changed his plea, agreeing to serve 25 to 30 years in prison for seconddegree murder. As for matt phelps, he will be back in court later this month. Until more answers are uncovered hi, everybody. Its lauren. Reporter laurens family is left waiting and wondering what went so wrong. A story we will continue to follow right here on abc. But we turn now to the devastation in texas, where abcs Michael Strahan met with just one of so many families who have lost everything but their lives. Do you stay in here and possibly drown . Reporter mindy benjamins family is one of the thousands in houston with no place to call home. One of the worst feelings as a parent is feeling helpless. You know, youre supposed to be there to protect them. My mom was crying. I just gave her a big hug. And i just told her i love her. Reporter the water rising, stranded for 14 hours before help finally arrived. So this is home. Whats left of it. I mean, this is your life. Everything. Reporter trying to salvage what they can. But they cant stay here. Its been day to day, changing hotels, calling, hoping you find a place like it was just maybe 35 minutes ago i finally found somewhere im going to stay tonight. Reporter 550,000 victims have now applied for Financial Assistance from fema, including benjamin. She was approved for a onetime 500 payment but still hasnt received it. So no assistance so far in any of this, and youre renting this house. Right. Reporter you had renters insurance. I had renters insurance. Reporter but did it cover flooding . Not a thing. Reporter but one things clear. This moms love for her family is Strong Enough to weather any storm. I vowed to them, were going to get through this. Whatever it takes. Whatever it takes.

Hard to believe for many of us, but were now approaching the 16th anniversary of the september 11th attacks. The motto that sprang up in the aftermath was never forget. While memories may be fading for some, tonight youre going to meet a man who remembers it all like it was yesterday and who wishes he could have done more to stop it. Former Port Authority detective matthew baa shaer is heading down new york citys west side highway on a trip he swore he would never make. Its not going to be easy. Reporter the skyline now dominated by the freedom tower, not bashears beloved twin towers. Theyre my buildings. I was Port Authority. I thought they were just stunningly beautiful. Reporter bashear has not been to manhattan since he helped at ground zero in 2001. The last time i was here this was nothing more than 15 stories of rubble. Reporter hes here confronting his darkest demons, sharing his story for the first time on network television. It doesnt get any easier. Its 16 years, and it doesnt get any easier. Because this should never have happened. This should never have happened. Reporter his story one of the many pieces of the september 11th puzzle put together in historys new documentary road to 9 11. I was hunting the guy that did this. And i didnt get him. My life has been forever changed. Reporter for bashear the road to 9 11 started in the 1970s when the World Trade Center was being built. As a child i would take my allowance and i would jump on the lirr local and i would watch them blasting and digging a whole for the foundation of the trade center. Sow really had a connection to these buildings. Yeah. I watched them being built, i worked there, and i sifted through the rubble for my 37 guys that i lost that day. Reporter his losses on september 11th were deeply personal. Working in the Port Authoritys intelligence unit, he says he knew a decade earlier that the World Trade Center would be a terrorist target. 1991 leading into 1992 i was asked by the Commanding Officer of the World Trade Center to do a vulnerability study. My report that i submitted was that the building was vulnerable to attack in the parking garages. Reporter were your warnings heeded . You complete the report and you pass it up the chain. What they do with it after that is their business, not mine. Reporter but just a year after basheers report watch out, watch out. One, two, three. Reporter more than 1,000 people were hurt and six killed when a bomb went off inside a van parked at the World Trade Center garage. It was an eye opener at that time. But of course as we get further down the road and other things have happened, it was really a huge warning sign. Reporter basheer would then team up with the fbi, eventually helping track down and capture the mastermind of the 1993 attack, ramzi yusuf, who gave Law Enforcement his own grim prediction about the twin towers the night they took him into custody in new york. It was february 7th, 1995, about 9 30 at night when we came around lower manhattan. And we took the blindfold off of him and said see, ramzi, theyre still standing. And he took the time to look us each in the eye in the helicopter. And he said, next time well have more money and we will bring them down. Reporter it would be yusufs uncle, Khalid Shaikh mohammed, or ksm, who would fulfill that promise six years later, working at the behest of al qaeda leader osama bin laden. We knew in the mid 1990s that Khalid Shaikh mohammed was trouble. Reporter Richard Clarke was the chief counterterrorism adviser on the National Security council at the time, overseeing the growing threat from al qaeda operatives like ksm. We were looking for him. And we had an indictment, a sealed indictment against him from a federal grand jury. Reporter he was wanted for his role in planning an attack on the pope and an elaborate plot to bring down planes over the pacific ocean. Both of those plots were foiled. To many of the people that knew him he was the boss. So when youre looking at somebody whos thought of that way youve got to put more effort into him. Reporter basheer along with his partner Frank Pellegrino crisscrossed the globe in the 1990s hunting terrorists including ksm. The u. S. Government tracked him to qatar in 1996 but clarke says when he requested help in capturing ksm he was turned down. We asked the fbi. We asked the cia. We asked the pentagon. Can any of you mount a snatch operation to go into doha and pick him up and fly him out . And all of them said that was not within their capacity. Reporter ksm would go on to handpick the 19 terrorists who hijacked the planes on september 11th. But trying to stop terrorists before they acted was not the only frustration in the years leading up to 9 11. Since there had never been a major foreign terrorist attack, a catastrophic attack, in the u. S. , even though the evidence suggested it could happen, a lot of people didnt believe, truly believe that it would happen. Oh, my god we just got a report in that theres been some sort of explosion at the World Trade Center in new york city. Reporter basheer had retired from the Port Authority in 2000. But he says when the first plane hit that morning in 2001 he knew exactly what was happening and who was responsible. And i felt my entire insides just fall out. And as i was standing there watching it i saw the second plane come in and hit. And i knew they came back. At that point i lost it. I just sank to the floor and i just started bawling. And as i was doing that, my phone rang. And it was my partner. He was crying too. And he said, bash, look what they did to us. Reporter basheer says he grabbed his gear, got in his car, and drove through the night to ground zero. What did you do . Initially, i didnt know what to do. I just i just knew i needed to do something. Reporter and you were allowed to do this kind of work even though you were already retired . Yes. The people from the Port Authority knew i was back. Actually, they told one of the range officers to sign out my old weapon and give it to me. Reporter he stayed for two weeks. When i drove out of manhattan that day, ive never been back. Reporter why not . Its too painful a memory for me. I live with a lot of guilt, that i let those guys down. That i lost a lot of good friends because i didnt get it done. Reporter Khalid Shaikh mohammed would finally be captured in pakistan on march 1st, 2003, and he is still imprisoned at guantanamo bay. For Matthew Basheer the lists of names at the 9 11 memorial are filled with stories he does not want the world to forget. Bruce reynolds. There wasnt a kinder, nicer guy than bruce reynolds. I need to keep their memory alive. Thats whats important for me. But they still did what they needed to do. They still needed to be gods warriors to get those people out of that building. But i never wanted to see their names etched like this. And currently airing on history, which is owned in part by our parent company, disney.
