When a Chicago man found his girlfriend in bed with another man, he went a little crazy.
He was so furious over the betrayal that he beat his girlfriend's lover unconscious and then lit his genitals on fire, police told DNAinfo Chicago.
"This will be a lesson to you, I lit your (genitals) on fire," the man told the 30-year-old, according to a police report. He reportedly used a Bic lighter to burn him while he was unconscious.
"The man ran to a laundromat at 44th Street and Ashland Avenue, where police found him applying Vaseline to the burned area in an attempt to sooth the pain, according to the police report," the Chicago Tribune notes.
The burn victim was taken to Holy Cross Hospital and later transferred to the burn unit at the University of Chicago Hospital, police say.
Police have not made an arrest in the bizarre case.
