Overview

• Chicago police say 52-year-old Michael Korosa was taken into custody Saturday and is scheduled for a detention hearing Monday at the Leighton Criminal Courthouse.
• The case stems from an Aug. 10 confrontation at the Clinton Green Line station in the West Loop that sent a 9-year-old, Elijah Flores, and a 22-year-old companion tumbling down the stairs.
• According to police and court documents, the 22-year-old was struck from behind with an object, described in one filing as a walking cane, which precipitated the fall that fatally injured Elijah.
• The Cook County Medical Examiner determined Elijah died of blunt-force head trauma and ruled the death a homicide after he was hospitalized at Lurie Children’s and later died.
• Authorities described the charges differently, with police citing a murder charge while court records list involuntary manslaughter and aggravated battery related to a transit incident, and a separate narcotics case involving Korosa remains pending.
