2nd person in custody in fatal attack of ex-Marine pushed into CTA train

Charges are pending against a second person who is being questioned in connection with the fatal attack of a former marine who was pushed into a Red Line train last week, Chicago police said Thursday.

The 19-year-old man was in custody and being questioned days after a warrant was issued for his arrest in the April 7 death of 29-year-old Mamadou Balde, police said.

Ryan Munn, 18, has already been charged with first-degree murder in Balde’s killing after he allegedly admitted to taking part in the attack, Cook County prosecutors said.

Balde was approaching passengers about 5:10 p.m. at the Jackson Red Line station platform when he started talking to Munn’s accomplice, prosecutors said.

Balde smiled and jokingly put his arms up as if to fight and the suspect punched Balde in the face, prosecutors said. Munn allegedly jumped in and the pair pushed Balde, who fell in between two train cars.

He was dragged along the platform until his head and upper body ultimately slammed into a metal partition inside a tunnel. He was pronounced dead at the scene.

Munn was arrested April 10 and denied bail at a court hearing Sunday.
