OAKLAND -- A man was found shot multiple times in the Trestle Glen neighborhood Sunday evening, though it was unclear where the shooting took place, police said.

Residents on the 950 block of Grosvenor Place near Underhills Road called police at 9:23 p.m. to report a man was down on the sidewalk, said Lt. Brandon Wehrly. He was found near a four-door Acura sedan suffering from multiple gunshot wounds, including one to the head, police said. No one in the neighborhood reported hearing gunshots.

Around the same time, the city's ShotSpotter technology detected gunfire in the area of 5th Avenue and International Boulevard, Wehrly said. Both incidents remained under investigation late Sunday, but Wehrly said it was possible the man could have been shot near 5th Avenue and International Boulevard and ended up in the Trestle Glen neighborhood.

The locations are about 1.6 miles apart and are directly connected by thoroughfares: 5th Avenue turns into Park Boulevard, which intersects with Grosvenor Place.

The man, who was not responsive, was taken to the hospital where he was listed in critical condition, police said.
