After two young men were strangled to death in an Illinois home, police arrived at the residence after receiving a tip on Thursday to find a group of people partying and playing video games, reported the Herald-News.

Police say the men were not only lured to the home, but that the murderers tried to dismember the bodies.

The police chief of Joliet, Ill., where the crime took place, called it a “disregard for common decency toward human beings.”

“It’s sick, it is sick,” a relative of one of the victims told NBC Chicago.

The two victims, Eric Glover and Terrance Rankins, may have been friends with the four individuals who have been arrested in connection with the deaths, one of whom is the son of the local police sergeant.

“I had chills all day long,” said Rankin’s mother, Jamille Kent, to the NBC affiliate after her phone calls to Rankin began to go unanswered.

The suspects, who police believe may have robbed Glover and Rankins, are being held on a $10 million bail.
