OAKLAND -- A woman and a man were wounded Monday in two West Oakland shootings that happened within seven hours just over a mile apart, authorities said.

Both victims are expected to recover from their wounds and police do not believe at this time that the shootings are related.

The 29-year-old woman was shot about 11:25 p.m. Monday as she sat in a car parked in the 800 block of 28th Street.

A man approached her car on foot and began shooting at her, with one of the rounds grazing her head, police said. She was taken to a hospital in stable condition, and the suspect fled. Police don't have a motive yet.

At 4:20 p.m., an 18-year-old man walking in the 900 block of Filbert Street was shot in the leg and buttocks by a gunman in a car. At least one errant shot also hit a home with a 69-year-old woman inside, but she was not injured.

The wounded man was driven by a passer-by to a hospital, where he was in stable condition.

The gunman got away. No motive was released for the shooting.

Police and Crime Stoppers of Oakland are offering up to $5,000 in reward money in each shooting for information leading to the arrest of the gunmen. Anyone with information may call police at 510-238-3426 or Crime Stoppers at 510-777-8572.
