A 20-year-old man was sentenced to 70 years in prison Tuesday for slicing his infant’s throat, then choking and stabbing his girlfriend to death in a jealous rage after she received phone calls from another man.
McKerry Coleman was convicted Oct. 14 by a Cook County jury of first-degree murder and attempted first-degree murder for the Nov. 30, 2009, attack in the 6700 block of South Evans.
Coleman was sentenced Tuesday to 70 years in prison -- 45 years for the murder of his girlfriend and 25 for the attempted murder of the baby, Cook County State’s Attorney’s office spokeswoman Tandra Simonton said.
Tanisha Edwards was killed when Coleman, her boyfriend, became upset that she was talking to another man on the phone. Both were home with their 7-week-old son when they began to argue about the call, prosecutors said.
When Edwards got yet another call from a man, Coleman, who was holding the infant in his arms, grabbed a knife and sliced his child’s neck, breaking the knife’s handle. He threw the baby to the ground and grabbed Edwards, beating her on the ground, court records said.
Edwards’ two brothers were home at the time and ran to get help, but it was too late. Coleman grabbed another knife and stabbed Edwards in the head and throat, killing her. Neighbors called police after seeing Coleman run away.
Edwards died several hours later, but the child survived.
Coleman turned himself him and gave a video statement confessing to what he did, prosecutors said.
