Chicago's Garfield Ridge / Summit / Argo Neighborhood - Homicide, 2 South Side shootings linked to pair of MINORITY ARMED ROBBERS - Store Clerk Ghassan K. Abujeries, 34, of Oak Lawn, was pronounced dead at 9:38 a.m. at Loyola University Medical Center

Two men are suspected in a string of violent incidents Wednesday morning including three shootings, one fatal; a carjacking; and a hit-and-run crash on Lake Shore Drive, Chicago police said.

The mayhem began about 7:25 a.m. in the 8900 block of South Chicago Avenue, when two men shot a 27-year-old man multiple times during a carjacking. They got away with a silver Pontiac Grand Prix with an Illinois license plate of L925050.

The man who was shot was taken in serious condition to Advocate Christ Medical Center in Oak Lawn, said Officer Ana Pacheco, a Chicago police spokeswoman.

About five minutes later, the two men -- now driving the stolen car -- shot a 24-year-old man in the 8400 block of South Mackinaw, police said.

At 7:50 a.m., they were involved in a hit-and-run crash with another vehicle in the 5700 block of South Lake Shore Drive. No shots were fired in that incident, police said. The silver car sustained front-end damage in the crash, police said.

They continued to suburban Summit, where at about 8:35 a.m. they robbed a gas station at gunpoint in the 5300 block of South Harlem Avenue.

At 8:50 a.m., they robbed another gas station ten blocks south, in the 7200 block of West 63rd Street. This time, one of the men fired his weapon, shooting and killing a cashier.

Ghassan K. Abujeries, 34, of Oak Lawn, was pronounced dead at 9:38 a.m. at Loyola University Medical Center, according to the Cook County Medical Examiner's office.

Police said the men left the scene in the silver Pontiac.
