CHICAGO (CBS) — Four men were killed and at least 10 other people were wounded in shootings across the city between Friday afternoon and Monday morning.

Most recently, a man was shot to death at 10:48 a.m. Sunday in the North Lawndale neighborhood on the West Side. James Morris, 23, was sitting in the driver’s seat of a parked minivan in the 1300 block of South Kedzie when a silver car drove slowly by and someone inside opened fire, according to Chicago Police and the Cook County medical examiner’s office. Morris, who lived in the same neighborhood, was shot multiple times and taken to Mount Sinai Hospital where he was pronounced dead at 11:15 a.m., authorities said. The silver car headed south on Kedzie after the shooting, police said. A police source said the victim was a documented gang member and the shooting is thought to be gang-related.

Earlier Sunday, a man was killed in an East Side neighborhood drive-by shooting that left another man hurt on the Far South Side. Two 18-year-old men were getting into a parked vehicle about 1:20 a.m. in the 10900 block of South Mackinaw when a silver Chevrolet Malibu drove by and someone inside fired shots in their direction. One man was shot in the back and taken to Christ Medical Center in Oak Lawn, where he was pronounced dead at 2:27 a.m., authorities said. His name has not been released. The other man suffered a laceration to his left ear, thought to be caused by shattered glass from the vehicle. He was taken in good condition to Trinity Hospital.

Shortly before 1 a.m. Saturday, two people in hooded sweatshirts opened fire into a crowd at a party in the 6500 block of South Drexel in the Woodlawn neighborhood on the South Side. Lance A. Jeffersons, 20, was shot in the face and torso, and a 37-year-old Samuel D. Head suffered a gunshot wound to the chest, authorities said. Both died at the scene, making them Chicago’s 100th and 101st homicide victims in 2017. A 29-year-old woman also suffered a graze wound to the thigh and was taken in good condition to Northwestern Memorial Hospital.

The weekend’s latest nonfatal shooting seriously wounded a 15-year-old boy Sunday night in the West Side Austin neighborhood. About 6:30 p.m., the boy was in the first block of South Mayfield when someone walked up and fired shots, police said. The teen suffered multiple gunshot wounds and was taken to Loyola University Medical Center in Maywood, where he was in serious condition.

At least seven other people were wounded in shootings across Chicago throughout the weekend.

Last weekend — an unseasonably warm Presidents Day holiday weekend — saw at least 37 people shot across the city, leaving five dead. More than 500 people have been shot in Chicago so far in 2017, according to Chicago Sun-Times data.
