The next story will also get you talking. It's disturbing. So is the music that some say inspired it.
The music is called Horrorcore and the lyrics are about murder, rape and Satan. Just entertainment or incitement to murder? You be the judge tonight.
And just when you thought Levi Johnston was only coming out of his shell to pitch pistachios, "Playgirl" called, he answered and apparently, well, he's going to, you know, show the full Monty. Details coming up.
(COMMERCIAL BREAK)
COOPER: In "Crime & Punishment" tonight, an aspiring Horrorcore rapper stands accused of cold-blooded murder and many are wondering if the music drove him to kill.
This is the alleged killer, suspected of taking the lives of a pastor and three other people. He is a follower of something called Horrorcore rap, a genre with lyrics that speak of extreme violence, torture and death.
Tonight we're going to take you inside the underground world of Horrorcore rap. Find out more about the appeal and whether it really did fuel one man's rampage.
Here is Gary Tuchman.
(BEGIN VIDEOTAPE)
GARY TUCHMAN, CNN CORRESPONDENT (voice-over): You might think Richard Samuel McCroskey (ph), looks like an average young man. But you'd be so wrong. On YouTube he calls himself Psycho Sam; his lyrics, offensive and upsetting.
For more upsetting is this -- Psycho Sam is now accused of actually carrying out the type of murder and mayhem he raps about.
JIM ENNIS, PRINCE EDWARD COMMONWEALTH ATTORNEY: Preliminary results of the autopsies indicate that the causes of death were blunt force trauma to the head.
TUCHMAN: The 20-year-old Northern Californian suspected of brutally killing four people had a smirk on his face as he led to jail in the tiny town of Farmville, Virginia.
One of the victims, 16-year-old Emma Niederbrock (ph) whom he met over the Internet and who invited him to stay at her house.
When a reporter asked McCroskey about the allegations against him, he declared...
UNIDENTIFIED MALE: Jesus told me to do it.
TUCHMAN: McCroskey has not yet made a plea. The attorney appointed to defend him on this murder rap who just visited him in this jail says...
UNIDENTIFIED MALE: He's dear (ph) in the headlights a little bit. I dare say he's -- he's -- I don't want to say in shock. That's a medical term. It's a big experience for him.
TUCHMAN: McCroskey has been involved in a musical genre that his lawyer and most other people know little about. It's called Horrorcore, a style of hip hop music that often dwells on topics that include killings, rapes and Satanism.
This concert features a group called the Insane Clown Posse, commercially a very successful group. Before we talked with them, the industry says there was not a connection between these lyrics and real life violence.
But these two teenagers feel differently. Landon and Brandon Maceachran are twins who are both close friends with Emma Niederbrock. A photo of Emma is still on one of the teens' cell phones.
Emma was a follower of Horrorcore, too.
(on camera): If she would have told you that she was inviting him to her house, a guy who writes these violent lyrics about murder...
BRANDON MACEACHRAN, FRIEND OF VICTIM: I would have been worried.
TUCHMAN: What would you have said to her beforehand?
MACEACHRAN: I would have been worried and I would have told her because I'm a blunt person. I would have told her that somebody needs to be around her to watch her.
If you have somebody that writes stuff like that, that's somebody you need to watch.
TUCHMAN (voice-over): Also bludgeoned to death, Emma's mother, Deborah Kelly (ph), Emma's father, the Reverend Mark Niederbrock (ph), a pastor at a Presbyterian church. And another friend staying with Emma, a teen named Melanie Wells.
(on camera): A disturbing sequence of events was triggered when police received a call from Emma's friend's mother. Melanie Well's mother hadn't heard from her daughter for a while and asked police to come by this house to check out the situation.
(voice-over): The cops came to the door, said they were met by the man known as Psycho Sam. They said he told them everything was fine that Melanie was at the movies.
But Melanie's mother still didn't' hear from her daughter. Called the police and told them please come back.
They came back the next day. This time Psycho Sam was no longer here. But a terrible odor was. Police went inside the house and immediately found three bodies. Upon further searching, they found a fourth.
This surveillance tape at the Richmond Airport shows McCroskey being arrested. He had fallen asleep near the luggage carousels.
(on camera): Richard Samuel McCroskey is scheduled to return to court on January 11th for a preliminary hearing. By then, he may find out if prosecutors plan to seek the death penalty.
(voice-over): His YouTube look was part of the act, but if the allegations against him are correct, this is how he may have really looked to four terrified people.

COOPER: Well, let's "Dig Deeper." Alan Lipman, a psychologist and the founder of the Center for the Study of Violence and James Zahn, the editor of Fangoria Musick and an authority on Horrorcore rap.
Appreciate both of you being us with.
Alan, you know, it's the easiest thing in the world to blame music for problems. Judas Priest used to get blamed, Marilyn Manson, even Elvin Presley back in the day have all been accused of inciting stuff. This music clearly it is offensive and the lyrics are disgusting. Does it really though cause somebody to kill?
ALAN LIPMAN, PSYCHOLOGIST: Well, look, here's the way it works. We've seen this not only with the music that you cited but with comic books, video games, with other music like Ozzie Osborne and so forth.
The fact of the matter is 98 percent of kids could be seated in front of this admittedly, very shocking hardcore and while they may be shocked by it, while they might be disturbed by it, they would not be violent. They just simply would not cause violence.
The problem is this, that in 2 percent of kids who already have a propensity towards violence, who are isolated, who are alienated, who are ready to act out; this is the match for the gasoline. So it provides basically a method and a means for violence.
So it's those kids -- and I do think that this is a situation where it applies -- where we have to be very careful in exposing these kids to this kind of music.
COOPER: James, do you agree with that? That it provides a language or way of thinking to a kid who has a pre-existing problem?
JAMES ZAHN, EDITOR, "FANGORIA MUSICK": I think that the bigger problem is that they have that predisposed penchant for violence or whatnot. But I don't feel that the music is that match. I think that entertainment as a whole -- and there is horror in many forms of entertainment -- looked at by that small percentage of people, maybe it could cause something. But I don't see it that way.
I tend to think that there's entertainment and there's real life. If you're going to do bad things, chances are you're going to do them with or without music.
LIPMAN: That's a very reasonable...
COOPER: I want to follow up on that for just a second. We have to take a quick break.
A lot more to talk about. Alan and James, we'll be right back to you.
Also ahead tonight, Michael Vick getting his own reality show -- talk about bizarre -- but does that guy deserve a platform? We'll let you decide.
(COMMERCIAL BREAK)
COOPER: He rapped about rape, torture and murder and now this young man who went by the name of Psycho Sam is behind bars charged with killing four people. He said Jesus told him to do it. Was the music the match that made him explode?
He was part of Horrorcore rap, the lyrics clearly sickening and disturbing, the message one of mayhem and bloodshed. With us is again is psychologist Alan Lipman and James Zahn, editor of Fangoria Musick and an expert on Horrorcore.
Alan you wanted to follow up on what James had said.
LIPMAN: Sure. I agree with James that for most people this is entertainment. But what we have to realize is that for kids who are already isolated and angry -- this is a kid who had already been thrown out of school twice, who had already shown anger, who said I hate everyone and hate everything that when he was, as we found out, rejected and his family split up, this kind of rage, as we've seen in the Secret Service study that was done in 2002 is expressed through the method and means of what they've listening to or doing, whether it is video games or whether it is hard core violent music.
That doesn't mean that we should ban this stuff.
James, you're absolutely right. The answer is to see the signs of this kind of anger and rage before this acted out in this way.
And this was a kid who was clearly showing signs of it long before these acts took place. So the answer is vision, intervention, treatment, not banning this kind of material. COOPER: James, I don't think most people have even heard of Horrorcore before. Maybe they heard of the Insane Clown Posse; that's about as close as I had heard of it.
Richard McCroskey, this guy who called himself Psycho Sam, he rapped about raping, torturing, killing -- is that standard fare for Horrorcore lyrics.
ZAHN: It can be. One of the things about Psycho Sam is that no one knew who he was before this incident. He wasn't a celebrity. He wasn't on any label of note. He wasn't out there selling tons of albums. He was very much a DIY type of independent underground artist that was doing this.
But as a whole, the genre is very much like the audio version of a really scary movie. There are all of those topics in there. Torture, murder, you name it, it's there. It's the audio equivalent to what horror films are on the visual end.
COOPER: What's been the reaction among people who like Horrorcore about this murder -- about these murders?
ZAHN: Everyone has been sympathetic. All the chat boards, and the message forums and all of that, everybody has expressed condolences and sympathy for the families. Because as Alan was saying, the norm would be not to go bludgeon people as he's accused of doing.
This is a small incident that once again, has brought attention to a larger genre but it's not a huge genre. Now it's mainstream news.
COOPER: Alan, you say you see parallels in this tragedy to others like Columbine and Virginia Tech. How so?
LIPMAN: Well, sure. All we have to do is walk backwards. Let's say we start -- we can start in the last ten years.
But let's start with Columbine. These were angry, isolated, alienated kids who had diagnosed mental illnesses that had not been treated. As the Secret Service report lays out, boom, boom, boom, boom. They were obsessed with doom, they immersed themselves in doom.
How would they have acted out that violence if they hadn't immersed themselves in that genre? And some other way, maybe they would have busted a window or maybe they would have gotten into fights. If this provides a direction, a means, a way of expressing the anger...
COOPER: So Alan, for a parent out there and their kid is listening to this and then maybe this is the first they're kind of hearing it, what do you advise?
LIPMAN: Long before the kid is immersing themselves in their room as he did for four years, from 1999 onwards, listening to hard core, see that when your child is absolutely distraught over your divorce, as his sister mentioned, that this is a situation that needs to be dealt with then, that needs to be intervened with them before it blossoms in to the kind of horror that we've seen over these last few weeks.
COOPER: We have to leave it there. Alan Lipman, James Zahn, it was good discussion. I appreciate both of you being on. Thank you.
LIPMAN: Thank you.
