(STMW) — A Loyola student killed in an attempted robbery and a 9-year-old boy were among victims in 15 separate shootings across the city since Friday evening.

The student, 23-year-old Mutahir Rauf, was shot in the 1200 block of West Albion at 7:50 p.m. Friday, police said.

He was with another person when two people walked up, showed a weapon and demanded his belongings, police said. At least one person then opened fire, striking Rauf in his chest and head, police said.

Rauf, of the 1400 block of West Pratt, was pronounced dead at the scene at 8:08 p.m. according to the Cook County medical examiner’s office.

In a post on EveryBlock.com, Ald. Joe Moore said the student was walking with his brother when the attempted robbery happened. The student thought the weapon was fake and tried to reach for it before being shot during the scuffle, Moore said.

Luigi Loizzo, a junior at Loyola, had taken an organic class with Rauf over the summer. He lives just 200 feet where the incident took place, the Sun-Times reports.

“It’s pretty scary that I have to look over my shoulder every time I walk outside,” said Loizzo, 20, of Addison.

Late Saturday morning, a 9-year-old boy was unintended victim of a shooting on the Near West Side, according to police.

The boy was walking with his father at 11:35 a.m. in the 2500 block of West Adams when a gunman opened fire on a passing black four-door car. The boy was struck “inadvertently” in the lower right leg, police said.

He was taken to Stroger Hospital in good condition. Police said the shooting likely is gang-related.

The most recent nonfatal shooting happened early Sunday in the Englewood neighborhood on the South Side.

The 29-year-old man’s thigh was grazed by a bullet about 4:30 a.m. in the 7500 block of South Union, police said, citing preliminary information. He was treated at the scene.

About 12:50 a.m., a woman was shot while driving away from her suspected shooters in the Austin neighborhood on the West Side.

The woman, 22, was in the driver’s seat of a parked vehicle in the 100 block of North Leclaire when two males–one armed with a gun–approached her about 12:50 a.m., police said.

The pair told the woman to get out of the vehicle. When she refused and drove off, one of them fired several shots in her direction and struck her in the arm, police said.

She drove about a half-mile to a gas station near Madison and Cicero, where she called police.

The woman was taken to Mount Sinai, where her condition had stabilized.

At least 11 others were injured in shootings since Friday night.

Additionally, a male was shot and critically wounded by police late Saturday in the Back of the Yards neighborhood on the South Side.

Police responded to the 4700 block of South Ada for a gang disturbance about 10:50 p.m., said Deputy Chief Carlos Velez, citing preliminary information. Officers saw several people, including a male armed with a handgun, Velez said.

When police responded to the scene, one man from the group began running, said Fraternal Order of Police spokesman Pat Camden. One officer then exited the passenger seat of his squad car and started chasing the man, who is thought to be in his 20s, Camden said.

“The officer repeatedly told him to drop his gun,” Camden said. “Instead, he turns with the gun and points it at the officer. He had no choice but to defend himself. And the officer opened fire.”

The male was shot three times, Velez said. A handgun was also recovered from the scene, according to Velez.

He was taken to Advocate Christ Medical Center in Oak Lawn, where he is listed in critical condition, Velez said.
