There is a growing call for change after a violent weekend in the East Bay, where authorities are investigating shootings in Oakland, Antioch and Bay Point.
The three shootings are believed to be unrelated, and authorities from each locale are asking for the public's help in tracking down the shooters.
In West Oakland on Saturday, a 38-year-old man was shot and killed at DeFremery Park as a McClymonds High School reunion picnic was wrapping up at about 7:30 p.m., police said.
Oakland police are investigating and urged anyone with information to contact the Homicide Section at 510-238-3821.
In Antioch early Sunday morning, a 30-year-old man was shot in the stomach on Huntsman Way and Whitetail Drive, police said. The victim was taken to a hospital, where he was in critical condition.
In Bay Point just before 6 p.m. Sunday, two people, including a baby girl, were shot and injured in what witnesses say was a drive-by shooting in the area of Desanie Circle and Laura Ann Court, Contra Costa County sheriff's deputies said.
