CHICAGO (CBS)– This long Thanksgiving weekend has seen a man stabbed to death, three men fatally shot and at least 18 people wounded by gunfire.

Christopher Jacobs, 19, died Friday afternoon after he was shot in the Back of the Yards neighborhood, authorities said. About 1 p.m. Thursday, someone called police to report numerous gunshots fired in the 4900 block of South Seeley Avenue, police said.

When officers arrived, they found Jacobs lying down on the street, police said. Jacobs was taken to Mount Sinai Hospital, where he died Friday at 2:15 p.m.

Around the time that Jacobs was shot on Thursday, Jonathan Belton, 25, was fatally shot in the 5500 block of South Albany Avenue, authorities said. Belton, of the 900 block of South Austin Boulevard, was dead on the scene.

On Wednesday, William Terry, 55, was stabbed multiple times when he tried to intervene in an argument between a married couple at 7:11 p.m. Demetrius Jackson, 32, was arguing with his wife near their home in the 10300 block of South Forest Avenue, authorities said when he allegedly took a kitchen knife and stabbed Terry multiple times throughout the body.

Terry, of the 14100 block of South Tracy Avenue in Riverdale, was declared dead at Advocate Christ Medical Center in Oak Lawn.

Jackson initially fled, but has since been arrested and charged with first-degree murder, according to police News Affairs. He will appear in bond court later Sunday.

On Sunday morning, two men were wounded — one of them fatally — in a drive-by shooting on the Near West Side. The shooting happened in the 2300 block of West Lake Street about 8:04 a.m., police said. Both victims, whose ages were not immediately known, were taken to Stroger Hospital, where one of them was pronounced dead, according to police.

Among the other 17 people wounded in shootings since Wednesday afternoon was a 15-year-old girl shot in the head.

The teenager was inside her home in the 1100 block of West 104th Street when shots were fired from outside and a bullet hit her about 9:35 p.m. Wednesday, police said. She was listed in serious condition at Christ Medical Center.

Also on Sunday morning a male riding in a car in the 2400 block of South Archer Avenue, near Chinatown, was shot in the leg in a drive-by attack about 4:25 a.m., police said. He was in “stable” condition, and no arrests have been made.
