CHICAGO (STMW) — Two people were killed and at least 26 others wounded in shootings across Chicago since Friday afternoon.

The most recent fatal shooting happened Saturday night in the South Side Park Manor neighborhood.

A 22-year-old man was sitting in a parked vehicle about 8:40 p.m. in the 400 block of East 72nd Street when two people walked up and one of them shot him multiple times in the side, police said.

An acquaintance drove him to Jackson Park Hospital and Medical Center, where he later died, police said. The Cook County medical examiner’s office confirmed the death but did not release his identity.

Detectives are questioning a person of interest in the weekend’s other homicide, which happened inside the 39-year-old victim’s Morgan Park neighborhood home on the Far South Side late Friday.

David E. Finney got into an argument with another person–only described as a male–who then pulled out a handgun and shot him in the chest about 10:35 p.m. at the home in the 11300 block of South Green, authorities said.

Finney was taken to Advocate Christ Medical Center in Oak Lawn, where he later died. Police called the shooting “domestic-related” and said a person of interest was being questioned Saturday afternoon.

The most recent nonfatal shooting happened early Monday in the West Pullman neighborhood on the Far South Side.

Two men, ages 17 and 20, were parked in a vehicle in the 12500 block of South Yale about 2:20 a.m. when two people got out of a dark-colored SUV and fired shots in their direction, police said. The shooters jumped back into the SUV, which sped away eastbound.

The 17-year-old was shot in the buttocks and the 20-year-old was shot in the leg and abdomen, police said. They drove themselves to Roseland Community Hospital, where both of their conditions had stabilized.

Early Sunday, four people were shot in a 35-minute spate of gunfire on the South and West sides.

At 2:35 a.m., a 30-year-old man was shot in the back in the Bridgeport neighborhood.

He was driving in the 3300 block of South Lituanica when shots were fired from a dark-colored car, police said. He drove himself to University of Chicago Medical Center, where he was listed in good condition.

About five minutes later, two men were shot in the Austin neighborhood on the West Side.

The shooting happened about 2:40 a.m., as the men–ages 21 and 22–were on a porch in the 5500 block of West Gladys when they heard gunshots and felt pain, police said.

The younger man was listed in critical condition with gunshot wounds to the buttocks and leg and the older man’s condition was stabilized with wounds to the wrist and ankle, police said. Both were treated at Stroger Hospital.

About 3:10 a.m., a 34-year-old man was shot in the Chatham neighborhood on the South Side.

Officers discovered the man–who has documented gang ties–lying in the street in the 8700 block of South State with gunshot wounds to his abdomen and leg. He was taken to Christ Medical Center, where his condition had stabilized, police said.

At least 20 other people have been shot between 3 p.m. Friday and early Monday.
