A man who was allegedly responsible for an accident that killed a Chicago man who had recently been released from prison is now facing a manslaughter charge.

The Cook County State’s Attorney’s office announced Tuesday that 25-year-old Christopher James Soto was charged with involuntary manslaughter in the July 10 death of 29-year old Kevin O’Brien.

Soto, who was being held in lieu of $250,000 bail, was being tried in the city’s Cook County Circuit Court on a manslaughter count.

Chicago police were called to a home on North State Street in the South Shore neighborhood shortly after 3 a.m. after a report of a possible injury, according to the police report.

A woman reported seeing a man falling down the stairs.

The man was pronounced dead at the scene.

The medical examiner’s office identified the victim as O’Briens.

Sotos was arrested about an hour later, after he left the home, the Cook County sheriff’s office said in a news release.

The cause of the accident remains under investigation.

O’Brian had just returned to his apartment from a friend’s birthday party when he was found lying in the living room, the release said.

His friend, Michael Zane, and a friend went into the kitchen to help him out of the house and discovered O’Malley suffering from multiple fractures, the news release said, adding that the victim was taken to Mount Sinai Hospital, where he was pronounced deceased.

The incident is under investigation by the Cook Crime Lab.
