A jury convicted an unlicensed daycare facility owner in Crystal Lake of causing an 11-month-old baby to stop breathing and breaking his ribs during an attack, which was caught on video taken by a “courageous” child witness. Migliorato applied pressure to the infant’s chest, causing a rib “or ribs” to be fractured, the complaint said. A grand jury indictment said the child stopped breathing and went limp when Migliorato forcefully applied pressure to his chest. The complaint said Migliorato strangled the infant by applying pressure to his neck, causing a lack of oxygen. A three-day jury trial began this week and ended with the jury finding Migliorato guilty of all charges following an hour of deliberation on Wednesday.
