Transcript for Student Was Drug User, Campus Police Drug Informant Before Death
Reporter: It's parents' weekend. Strolls on the quad, fall foliage on the bucolic campus, an idyllic scene. But nearby in off-campus housing, a dark scene is unfolding. College junior Logan is discovered dead in his apartment. The campus of mass amherst is reeling. Vice chancellor for university relations John Kennedy remembers the day. To have a death happen, what was that like? It's incredibly shocking, it's heartbreaking. Logan himself was incredibly well liked. He was a good student. It's stunning when something like this happens. Reporter: The news spreads like wildfire, and piques the interest of fellow students like Eric Bosco, an earnest 21-year-old journalism major who dreams of a career at a big city newspaper. There was an e-mail sent out to the campus community telling us that a student had died in his off-campus apartment. But there was no information about how exactly he had died. I had been asking around and began to hear rumors. This story published -- Reporter: Eric is taking a class in investigative journalism with professor Steve fox. Eric and another classmate make the curious case of Logan's death their class project. So you started sniffing around. How long did it take to start getting information? Well, I went down to mass police and requested all documents relevant to his name. Reporter: Did they just hand them over? After a few days. You know, they made the copies and they turned everything over, yeah. Reporter: They are public documents. But it's only this enterprising young reporter who asks to see them. Easy to obtain, and impossible to forget. Were you shocked by anything that you read in there? I was. Reporter: In those police records, secrets of a turning point in Logan's life. Details of a night ten months before his death. At the time, Logan is a sophomore living in a dorm. He is dealing drugs and campus police have noticed. So one cold winter's night Logan unwittingly sells an undercover officer two tabs of lsd for $20. The gig is up. So an undercover police officer comes in here. Yep. Reporter: At night, buys some lsd. Yep. Reporter: And they search his room at that point? Correct. Reporter: And what do they find? They find $700 in cash, an assortment of drugs, and a hypodermic needle. Reporter: At mass amherst, a discovery like this one would typically lead to arrest, suspension. And according to school policy, a phone call to his parents. But on this night, for Logan, campus police choose to do something different, very different. And they made him an offer. What was the offer? The offer was they'll drop all charges and they won't charge him with distributing lsd and for the possession of drugs in his room if he wears a wire and goes, makes a controlled buy from a higher-level dealer on campus. Reporter: At another dormitory? Correct. Reporter: To Logan it's not much of a decision. Not only does he face charges, he faces having to pay back $40,000 in scholarship money. He takes the deal. Police identify him as "Confidential informant number eight." That same night, police direct him to contact his former roommate, a friend called "Sleepy Dan" and arrange to buy $70 worth of lsd. This is where Logan then comes. Yes. Reporter: After texting sleepy Dan. Yes. Reporter: And he's wearing a wire. When he gets up into the room, he's wearing a wire. He makes the buy. He leaves the room. And detectives swoop in and make the arrest. Reporter: What timeframe are we talking about? Like, how quickly after Logan goes in and makes the buy from sleepy Dan, in this dormitory -- Matter of minutes. Reporter: In a matter of minutes the police are in there right away. Right. Reporter: That must have caused a lot of commotion. It's a crowded dormitory, filled with students. Not so confidential. I guess not. Reporter: No secret on campus but a huge secret to Logan's mom Francesca. She's kept entirely in the dark about just how dark her son's college experience had become. You were the one who told Logan's mom that Logan had worked as a confidential informant? Correct. Reporter: How hard was that to do? That was probably the hardest thing I've ever done. She started to cry. It was just a powerful, tragic moment. Reporter: I'm not sure "J" school, journalism school, actually prepares you for tasks like that. I'm not sure anything can prepare you for that. I miss him. Really miss him. Reporter: Francesca is now determined to help Eric. She sends him Logan's cracked iPhone. What did you find? We found a lot. This kid hadn't deleted any text messages for a year and a half or two years that he had the phone. He was able to essentially speak from the grave. Reporter: Logan's texts make clear, taking the deal has taken a toll. The life of the party has become a campus pariah, a guilt-ridden Logan writes a friend -- "Kind of hard to live with myself. That was honestly the worst day of my life." He was paying a big price as that rumor got around campus about his role in the arrest of a fellow drug dealer. Right. Reporter: A friend texts "You're just a really really selfish . Logan writes "Don't hate me, hate the system for making me an offer I couldn't refuse." To another friend, "I'm thinking transfer out of mass though. Everyone hates me now." Logan confides in his childhood friend John Neuwirth. He wasn't happy about what he did. He was ashamed. He felt bad. As anybody would. He gets labeled as a snitch, labeled as a rat. It's basically ostracizing him from the community. One tenth afr Logan is made confidential informant 8, the police are in touch with Logan him again. They are returning that $700 they took from his dorm room. The news seems to brighten Logan's dark mood. In a text Logan writes "Cops R giving me my money back! And we're in business!" And that he then went and used that money to buy drugs. Right. Reporter: Money that, had he been arrested and had you been called, he would never have been able to use to purchase drugs. No, he wouldn't have been. Reporter: Instead, Logan stays at mass, and soon comes the most dire of all of his texts. "I'm a heroin addict," he confesses to a friend. School's out." But he keeps all of this a secret from his mother. At the same time he is asking his mother for lasagna, the night before parents' weekend, ten months after he went undercover, he sends a message to a dealer desperate for a fix -- "My veins are crying. Is the traffic going to be bad?" The dealer responds "You will very soon be in the loving comforting arms of miss H." By the next morning, Logan, just 20 years old, is dead. Reporter: Where was Logan found? In the bathroom. Reporter: On the floor? Yes. Nearby, there was a spoon and a needle. Reporter: It is a fate Francesca is certain could have been avoided if only she had been given a chance. We should have been called, under the policies and procedures of the university. I would have been up there in the middle of the night, bringing him home and finding him help. Just knowing there was a syringe, I would have just automatically made an assumption it was heroin. Reporter: So, do you think he died because he was a confidential informant? Yes. Reporter: Not because he was a drug addict? No. Reporter: Why? It's ten months that passed. If the policies and procedures were adhered to, I would have been alerted to this. He would have gotten help. Reporter: Next, a hockey mom with a power play, on a mission pitting herself against a prestigious university. You don't think these parents have a right to know that their child is being used as a confidential informant? Well -- Reporter: While on a college campus? And, who was Logan's dealer who dealt him that lethal dose of heroin? The answer is the last thing mass wants to hear tonight. Stay with us.
