Hamilton, of south suburban Flossmoor, alleged shot Means and Bankhead in the basement of a building in the 8200-block of South Houston Avenue. Their bodies were found Saturday at 10:30 a.m., according to police. Both had been shot in the head, the Cook County Medical Examiner's office said.
Means' mother, Camille Cochran, said that Hamilton and her son had exchanged words on Facebook.
"An argument led to this, that's crazy," said Cochran, 42, to the Chicago Sun-Times. "Now, I don't have my son no more."
Hamilton was ordered held without bond Tuesday afternoon.
