Bail was set Monday at $750,000 for a Sauk Village mother accused of killing her teenage son during an argument Saturday over ice cream, authorities said.
Robin Erwin, 31, was charged with first-degree murder for stabbing her son, Diontae, 17, to death at their home in the 1700 block of 223rd Street, Sauk Village police said.
Diontae Erwin was pronounced dead at 12:41 p.m. at Franciscan St. Margaret Health in Dyer, Ind., according to the Lake County, Ind., coroner’s office. It said he died from a stab wound to the chest and his death was ruled a homicide.
Witnesses said the mother and son were arguing about ice cream about 12:15 p.m. when the stabbing occurred, prosecutors said.
Robin Erwin called police and told them her son had walked into the knife, a claim that the coroner’s office said was inconsistent with the medical findings.
Police said their investigation into the fatal stabbing led them to arrest Larry Gray, 21, who was charged with unlawful use of a weapon by a felon and violating parole.
Officers also seized about 130 grams of marijuana from the Erwin home, according to police.
