The Cook County State’s attorney’s office brought a charge of first-degree murder after the Lake County, Ind., medical examiner’s office determined the knife had entered under Diontae’s clavicle and pierced his heart.
Witnesses overheard an argument about ice cream shortly before the incident, prosecutors said. Bond was set today in the Markham courthouse at $750,000 for Erwin.
Robin Erwin’s mother and Diontae’s grandmother, Ruth Erwin, declined to comment this afternoon. A makeshift memorial of balloons, signs and a stuffed bear sat under a tree in the front yard of the ranch-style home.
Police said they found Diontae about 12:15 p.m. Saturday. The boy was taken to Franciscan Saint Margaret Health in Dyer, Ind., where he was pronounced dead at 12:41 p.m.
Authorities seized 130 grams of marijuana from the home and also arrested Larry J. Gray, 21, for violating his parole on a conviction for unlawful use of a weapon.
Two neighbors said this afternoon that they often hear loud arguments at the home and front yard. Renard Williams, who lives across the tree-lined street, said the Erwins moved to the neighborhood about 18 months ago and police have visited the home several times. Sauk Village police referred all questions about the incident to the Cook County state’s attorney’s office.
Jerry Willoughby, who said he has lived in the neighborhood for 37 years, agreed the Erwin home has been the source of noise problems and frequent visitors, including from authorities.
Williams, who has two sons, said he wishes things had turned out differently for the Erwins. “I’m sad about that incident,” he said, “but I’m glad I told my boys to stay away from over there.”
