CHICAGO (CBS) — Fifteen shootings were recorded in the first 12 hours of Chicago’s weekend that left four people dead and another 16 wounded across the city.

Nykea Aldridge, a cousin of Chicago Bulls star Dwyane Wade, was shot to death Friday afternoon as she pushed one of her children in a stroller in the Parkway Gardens neighborhood on the South Side.

Aldridge, of the 6400 block of South King Drive — colloquially referred to as “O Block” — was taken to Stroger Hospital with gunshot wounds to the head and arm and was pronounced dead at 4:15 p.m., according to police and the Cook County medical examiner’s office.

About 3:30 p.m., Aldridge, 32, was walking with a baby in a stroller and a man in the 6300 block of South Calumet when two male suspects walked up and fired shots at a third man, according to Chicago Police.

“As she was walking down the street some type of altercation occurred which didn’t involve her,” Deputy Chief of Detectives James Jones told reporters at Chicago Police headquarters Friday night.

A 55-year-old man was killed in a shooting Friday evening in the Uptown neighborhood on the North Side, police said.

He was shot in the upper right arm at 6:13 p.m. in the 900 block of West Wilson, according to police. He was taken to Illinois Masonic Medical Center where he was pronounced dead at 6:51 p.m., according to police and the medical examiner’s office.

Minutes earlier, Romon M. Tolbert, 35, was standing on a corner in the 1500 block of North Meade Avenue when a male got out of a vehicle and approached him shooting, according to police and the medical examiner’s office. The shooter then got back in the vehicle and drove away.

Tolbert, of the 200 block of North Kildare Avenue, was shot in the head and chest and was taken to Mount Sinai Hospital where he was pronounced dead at 6:49 p.m., authorities said.

Two men were shot — one fatally — in the West Pullman neighborhood on the Far South Side early Saturday, police said.

The two, ages 21 and 24, were driving home in an allery in the 500 block of West 127th Street about 3:35 a.m. when a male with dreadlocks shot them as he was inside a blue truck, police said.

Both were taken to Christ Medical Center in Oak Lawn. The younger man was shot in the shoulder and later pronounced dead at the hospital, police said. The other man was shot in the leg. His condition stabilized. Additional details were not available early Saturday.

The most recent nonfatal shooting left a teen boy and two men wounded in the Austin neighborhood on the West Side.

The three were eating as they sat in a car in the 5400 block of West Ferdinand about 3:05 a.m. when someone walked up and shot them, police said.

The teen boy was shot in the right arm and also suffered a graze wound to his left arm, police said. One man, 22, was shot in the left knee, while the other man, also 22, was shot in both feet.

All three were taken to Mount Sinai Hospital in good condition, police said.

At least 12 other people have shot across the city since Friday afternoon and the Chicago Sun-Times’ weekend shooting tracker will be updated throughout the weekend as shootings are confirmed.
