Four teens who allegedly brutally strangled two men and tried to dismember them are caught by cops playing videogames in gruesome death lair.

Lying nearby the festive party atmosphere were the semi-mutilated bodies of two friends, Eric Glover and Terrence Rankins.

The victims’ remains were recovered by police inside a home at 100 North Hickory Street in Joliet, Illinois. 

Cops believed the accused teen killers lured their vics into the home and killed them after trapping them inside.

“'This is one of the most brutal, heinous and upsetting things I've ever seen in my 27 years of law enforcement,” Police Chief Mike Trafton told media.

“Not only the crime scene, but the disregard for common decency toward human beings.”

Police said the victims, Joliet natives, Glover and Rankins, both 22, were lured to the home of Alisa Massaro, 18.  They were then robbed and then killed.

Investigating officers discovered the bodies when they were called to the home, where they found Massaro playing video games with Adam Landerman, 19, and Joshua Miner, 24.

All three were arrested on first-degree murder charges and Bethany McKee, 18, of Shorewood faces the same charges.

The accused are being held on $10 million bond.

Ironically, one of the accused killers, Adam Landerman's mother is a police sergeant in the area, but her superiors immediately said that she wouldn’t be involved in the ongoing investigation – at all.

While the victims were both black and the accused killers white, cops say, race wasn’t an issue.

Charles Pelkie, spokesman for the Will County State's Attorney's office, said State's Attorney James Glasgow will personally prosecute the case, as he did former police officer Drew Peterson's.

Jurors convicted Peterson in September of first-degree murder in the 2004 drowning death of his third wife, Teresa Savio.
