An unsuspecting motorist was killed by an apparent stray bullet as he drove — sending his out-of-control SUV veering into a female pedestrian in Queens on Monday, cops said.

William Alcindor, 66, was driving a 2014 gray Nissan east on Baisley Boulevard and turning onto northbound Farmers Boulevard in St. Albans around 4:50 p.m. when he was struck in the head by a slug that investigators believe was meant for someone else, police said.

The mortally wounded senior lost control of his ride and slammed into a 23-year-old woman, cops said. 

Alcindor — who lived about 2 miles away in Cambria Heights — was taken to Jamaica Hospital Medical Center, where he was pronounced dead, police said.

The female pedestrian, who suffered leg injuries, was taken to the same hospital, where she was listed in stable condition, cops said. 

The suspected shooter — seen in a photo released by the NYPD early Tuesday — is described as having black hair, a medium complexion and slim build, weighing about 150 pounds. 

He was last seen wearing a black shirt, black pants, white sneakers and a black surgical mask, cops said.

Investigators believe the young gunman was with at least two other people — but the exact number remains under investigation as cops review video, police sources said.

The motive for the shooting remains unclear, and it’s unclear exactly whom he intended to shoot, cops said.

No arrests had been made by Tuesday morning.

Anyone with information on the suspect is asked to call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782).
