OAKLAND -- Four shootings within five hours Friday in East Oakland left a 21-year-old Hayward man dead and three other men wounded, police said Saturday.

The shootings are not believed to be related, police said.

The victim of the fatal shooting was identified as Rashad Meredith. He was found shot about 9:15 p.m. Friday in his car in the 9600 block of Birch Street. The car, which had run into a pole, was engulfed in flames. He later died.

A 21-year-old Oakland man was found with a leg wound a short distance away on Birch Street. His name was not released, and he was treated at a hospital and released.

Police said Meredith used to live in Oakland and may have been in the area visiting relatives or friends. Investigators said the wounded man did not know Meredith and was in the neighborhood to meet someone when he was hit by an apparent stray bullet.

Police said some cars and houses on Birch Street were also hit by gunfire, but no one else was wounded. Police said they do not have a motive for the shooting, and no arrests have been made.

In the other shootings, neither victim suffered life-threatening injuries and were in stable condition at hospitals. No motive or arrests have been made.

One happened at 6:30 p.m. when a man was shot in the 8000 block of International Boulevard.

The other happened at 4:30 p.m. when a man was shot in the 1600 block of 92nd Avenue.

The homicide was Oakland's 95th of the year. Last year at this time, there were 89 homicides in Oakland.
