“Hearing the constant gunfire, many of you may feel hopeless, frustrated, and fearful,” Armstrong said in a news release. “As your chief, I refuse to give up! OPD needs your (local residents) help to reduce the violence in our city.”

Gunfire erupted on Oakland streets at 12:45 a.m. Friday. Officers responded to the 2300 block of 55th Avenue to investigate the report of a male lying on the ground. Once on scene, officers located an unresponsive male suffering from gunshot wounds.

The man died at the scene.

Less than four hours later, officers were investigating a second homicide. Around 4:15 a.m., officers were dispatched to the 1400 block of 3rd Street to investigate the report of a shooting.

Upon arrival, officers located an unresponsive male suffering from a gunshot wound. He also was declared at the scene.

“As a lifelong resident of Oakland, I am deeply saddened each time a person is killed in our city,” Armstrong said of the homicides.

Over the next 13 hours, officers investigated seven separate shootings with a total of 10 victims.

The first incident happened just before 2:00 p.m. when officers responded to the 7300 block of International Avenue and discovered a male victim suffering from a gunshot wound.
