The crew, which called themselves the Latin King Goonies (not affiliated with the actual Latin Kings), apparently just decided to do it all for kicks. Police say they first kidnapped a 17 year-old who they believed was gay. He was "thrown into a wall, made to strip naked, hit in the head with a beer can, cut with a box cutter and sodomized with the wooden handle of a plunger." Then, they kidnapped another 17 year-old, and a 30 year-old man they believed had been his lover. They forced the teenager to "hit him and burn him with a cigarette." And more, from the NYT:
The assailants also brutalized the 30-year-old, hitting hit him with a chain, sodomizing him with a small baseball bat and forcing him to drink 10 cans of the beer they asked him to bring to the party - a brand called Four Loko, Mr. Kelly said. While holding the man hostage, the attackers took his keys, went to his apartment and robbed his brother of $1,000 and two debit cards, [Police chief Ray] Kelly said.
People need to try being nice once in a while.
