A man was killed and another young man shot in the head in separate South and Northwest side shootings about the same time Sunday night, authorities said.

The shooting death was the third gunshot wound homicide in Chicago since 11 a.m. Sunday -- one happened about 11:30 a.m. and the other about 5:10 p.m.

The man killed, 19-year-old Junior Estudillo, was shot about 10:10 p.m. near the intersection of School Street and Keeler Avenue in the Kilbourn Park neighborhood while he was in a car with two other people, police said.

Estudillo was pronounced dead about 12:15 a.m. at John H. Stroger, Jr. Hospital of Cook County. He was shot in the abdomen, police said.

The other two people in the car – a 19-year-old shot in the face and shoulder and a 25-year-old man shot in the back and buttocks – are still alive. A friend of the three drove them to Norwegian American Hospital and they were transferred to Stroger.

Someone walked up to the car and opened fire, police said, though it's not clear if the car was moving at the time of the attack.

About the same time in the Lithuanian Plaza neighborhood on the Southwest Side, an 18-year-old was shot in the temple while standing near a bus stop at 69th Street and Western Avenue.

He's in critical condition at Advocate Christ Medical Center, police said.  A westbound CTA bus driver making a left turn onto Western Avenue saw young men or boys running across the street and then saw the 18-year-old in the street.

"I really didn't see much. It looked like he was having a seizure," said Rosalind Brown, the bus driver, of the man shot. "The boy was laying in the middle of the street, right by the side of the bus stop."

It's not clear if police were able to get usable video from cameras on the bus. The boy was shot across the street from a police department blue-light camera, mounted atop a traffic light pole and just east of another one a bit west on 69th Street.

Police held the bus until about 11:35 p.m. An evidence technician showed up at the scene a short time after the bus left. A CTA supervisor lingered at the scene while the evidence technician took photos and looked for evidence.
