Paolilla, who was 17 years old when the four teens were killed, is on trial for the murders. The jury in her case saw video and photos from the crime yesterday, which prosecutors say was motivated by drugs and money.
In court yesterday, Paolilla's attorney blamed Snider, her then boyfriend, for being the person behind the crimes.
In opening statements, Paolilla's attorney described Snider as the bad guy who had control over a teenager who felt a little lost in the world.
"The parents see it and they tried to prevent this person from coming over to her house to seeing their daughter, who was 14 - 15 year old at the time, and is parting her away from the influence of her parents," said defense attorney Mike DeGeurin.
Snider is not on trial for the murders because he is dead. He committed suicide in 2006 after he was charged with the murders. The prosecution says Paolilla acted on her own will and beat one of the victims with a gun after she ran out of bullets. That victim was her best friend.
If convicted, the now 22-year-old faces life in prison
