Three people were killed and six more were injured Wednesday in shootings across Chicago.

An 18-year-old was shot to death in a Logan Square apartment on the Northwest Side.

About 10:43 p.m., Brandon Delgado was in a second floor apartment in the 2200 block of North Avers Street when several males walked in and fired shots, Chicago police and the Cook County medical examiner’s office said. The shooters then drove off in a gray sedan.

Delgado was pronounced dead on the scene with multiple gunshot wounds to the body, police said. Area North detectives are investigating.

Less than an hour earlier, three people were struck in a shooting that left a teenage boy dead.

Parrish Dejean, 17, and the two others were southbound about 9:50 p.m. in the 7500 block of South Lafayette Avenue when someone in a white sedan fired shots at them, police and the medical examiner’s office said.

They continued driving to the 7400 block of South Stewart Avenue in Englewood where they called police and the Chicago Fire Department, police said. Parrish sustained a gunshot wound to the head, and an 18-year-old was shot in the back. The third male, whose age is unknown, was shot in the chest.

Parrish and the 18-year-old were taken to University of Chicago Medical Center in critical condition, and Parrish was pronounced dead at 11:30 p.m., police said. The third male took himself to the same hospital with a gunshot wound to the chest.
