Police are investigating four separate shootings that left one man dead and six other people injured in the city late Friday and early this morning.

The man was identified as Francisco Rufino, 22, according to the Cook County medical examiner's office. He was pronounced dead at 3:19 a.m. at John H. Stroger, Jr. Hospital of Cook County, according to the medical examiner's office.

He was with another man when the shooting happened at 10:30 p.m. in the 1800 block of West 19th  Street in the Heart of Chicago community, said Chicago Police Department News Affairs Officer Hector Alfaro. Rufino lived in the 1800 block of West 17th Street, according to the medical examiner's office.

The two were inside a vehicle that was westbound on 19th Street when they heard shots ring out and the driver, 28, was hit in the right arm and the 22-year-old passenger was hit in the head, Alfaro said.

The 22-year-old was transferred to Stroger while the older man, whose condition was serious but had stabilized, remained at University of Illinois at Chicago Medical Center, where they were both treated initially, the officer said.

The shooting is gang-related, according to Alfaro, who said no one had been arrested early Saturday.

• About 3 a.m. a 22-year-old man showed up at Provident Hospital of Cook County with a gunshot wound, according to police. He claimed he was shot in the 7500 block of South Rhodes Avenue in the Chatham neighborhood on the South Side, but police are not sure if that is the case.

• Two people were shot in the 1200 block of West 72nd Street in the city's Englewood neighborhood about 1:30 a.m., said Alfaro. A 16-year-old boy was shot in the chest and was seriously hurt while the second victim, a 20-year-old man, was shot in the wrist, police News Affairs Officer Michael Sullivan said.

Both were taken to Stroger hospital, where their conditions were stabilized.

The two were standing on the street when someone drove past in a dark-colored van and fired at them, Sullivan said.

• About 12:45 a.m., two men who reported being shot near Armitage and Kedzie avenues in the Logan Square neighborhood arrived at Presence Saints Mary and Elizabeth Medical Center for treatment, according to police.

The men were inside a light-colored car traveling west on Armitage when shots were fired from a light colored sport-utility vehicle, said Alfaro.

The driver, 34, was shot twice in the head and was listed in critical condition at Stroger hospital. The other man, also 34, suffered a graze wound to the head and his condition had stabilized at Stroger, Alfaro said.

The attack appears to be gang-related, said Alfaro, who said no one is in custody.
