Chicago shootings have left four men dead since early Saturday afternoon, among them two teens and a 66-year-old, according to authorities.
The most recent shooting happened about 2:40 a.m. in the 8000 block of South Elizabeth Street, police said.
Authorities said an 18-year-old man, later identified as Deandre Baber, was standing on the sidewalk when someone opened fire from across the street, striking him in the head.
Baber, who lived in the 7300 block of South Winchester Avenue, was pronounced dead on the scene at 2:58 a.m., according to the Cook County medical examiner's office.
About midnight, a 29-year-old man was fatally shot in the 400 block of West 117th Street, according to police.
The man, identified by the medical examiner's office as Maurice Coleman of the 11000 block of S. Lowe Avenue, was walking with a friend when someone fired shots, striking him in the head and chest, according to police.
He died on the scene about 12:20 a.m., according to the medical examiner's office.
This morning's homicides followed the fatal shooting Saturday afternoon of a 66-year-old man in the 2300 block of West 57th Street.
Police said the victim was shot multiple times about 2 p.m. during a possible robbery. A witness heard gunshots and then saw the victim lying on the ground in the street. He was pronounced dead a short time later at Mount Sinai Hospital, police said.
The assailant or assailants "knew he had money,'' police said.
The man, identified as Herbert Goode of the 12500 block of S. 89th Avenue in southwest suburban Palos Park, was shot in the neck in what was possibly a robbery or robbery attempt, said Chicago Police Department News Affairs Officer Daniel O'Brien.
Police blocked off 57th Street at Oakley Avenue as they investigated.
Two witnesses, who did not want to be named, said they pulled up to a mechanic's shop at the intersection and saw a light blue car driven by a black male with dreadlocks go speeding by them, almost hitting them.
As they approached the mechanic's, they saw several people run out of the shop toward a red van. An older man was lying on the ground with blood in his shirt.
The man appeared to be moving and responding to people as police arrived, the witnesses said.
Also on Saturday afternoon, 18-year-old Michael Munoz was pronounced dead at 1:21 p.m. at John H. Stroger, Jr. Hospital of Cook County after a shooting in the 1700 block of West 46th Street in the city's Back of the Yards neighborhood, authorities said. Munoz lived in the 6000 block of South Kolmar Avenue, according to the medical examiner's office.
The victim was walking on the street when an unknown assailant got out of a van, pulled a gun and shot him about 12:40 p.m., said News Affairs Officer Veejay Zala.
The gunman got back into the van and fled the scene of the attack, which police said was gang-related.
Separately, a 49-year-old man and 17-year-old boy were injured in two shootings early Saturday evening, police said.
The 49-year-old was shot about 5:20 p.m. in the 9000 block of South Bishop Street in the city's Brainerd neighborhood, according to preliminary information, said Zala.
The man was hit in the back, chest and side, and transported to Advocate Christ Medical Center in Oak Lawn in serious condition, Zala said.
About 5:15 p.m., a 17-year-old male was shot in the left calf while walking in the 1900 block of South Hamlin Avenue in the city's Lawndale neighborhood, Zala said.
He was taken in good condition to Mount Sinai Hospital, Zala said, and told police that an unknown attacker approached on foot and shot him before fleeing the area.
