A convicted felon was released Monday ahead of his trial after being charged in an attack last month at a Green Line station downtown that left a 9-year-old boy dead.

Michael Korosa, 52, is charged with a felony count of involuntary manslaughter in the death of Elijah Flores, Cook County court records show. He was also charged with another felony for allegedly battering a transit employee.

Surveillance video captured Elijah and his caretaker, Jonah Soria, exiting a Green Line train on the morning of Aug. 10 while Soria was arguing with Korosa and another man, according to a police report.
