(CHICAGO) A 34-year-old man turned himself in to police after he shot his ex-girlfriend to death and drove off with her two kids Tuesday night in the South Shore neighborhood.

Mechelle Lewis, 28, was sitting in a minivan parked on the block where she lived in the 7200 block of South Bennett about 9:50 p.m. when her ex-boyfriend walked up and fired into the vehicle, according to police and the Cook County medical examiner’s office.

Lewis was pronounced dead at the scene at 10:11 p.m., authorities said.

The ex-boyfriend then took her 8-year-old daughter and 5-year-old son and drove off in a light-colored minivan, police said. He drove to the Grand Crossing District police station at 7040 S. Cottage Grove Ave., where he turned himself in to police custody.

The children were not hurt and a weapon was recovered from the vehicle, according to police. Charges were pending Wednesday morning.
