The young man took off running and then pointed a "a large revolver" at pursuing officers, according to a statement released by the police department.



"It turned out to be a .44 caliber revolver with an 8- or 10-inch barrel," Fraternal Order of Police spokesman Pat Camden said. "A Dirty Harry-looking gun."



Officers fired and hit him, police said. He was pronounced dead about 10:10 p.m., according to the medical examiner's office, which did not release his name immediately.



The first police shooting Friday occurred around 4 a.m. when an officer wounded a man during a chase down an alley in Englewood, authorities said.



Police had responded to a 911 call of a man with a gun at 74th Street and Princeton Avenue, Camden said. When a beat car pulled up, Dominiq Greer, 23, ran off and an officer chased him into an alley just east of Vincennes Avenue and north of 75th Street, he said.



Greer threw the gun while fleeing police, causing it to discharge, according to Cook County court records. A police officer returned fire, according to prosecutors.



Greer remained hospitalized Sunday. He was charged with unauthorized use of a weapon by a felon and ordered held on $150,000 bail.



Police took a gun into evidence from the scene, according to Camden. "That's the one guarantee in life. You shoot at police, they're gonna shoot back," he said.



Later in the morning, around 11:25 a.m., police shot and wounded a man in the 1500 block of West Birchwood Avenue in Rogers Park, officials said.
