At about 9:30 p.m. police responded to a call of a victim down in the 1100 block of Ocean Avenue, near Alcatraz and San Pablo avenues in Oakland, Oakland police Officer Holly Joshi said.
Officers found a 54-year-old Oakland man with stab wounds. The man was transported to a local hospital but later succumbed to his injuries.
Oakland resident Tamara Warren, 39, is wanted in connection with the homicide, Joshi said. She is described as a heavyset black woman standing 5 feet 2 inches and weighing approximately 200 pounds with brown hair and brown eyes.
The Alameda County coroner's bureau has identified the victim, but has not released his name due to the pending police investigation and notification of next of kin.
The stabbing is Oakland's 53rd homicide this year and the first this month. Overall, violent crime in 2010 is down 16 percent compared to this time last year, Joshi said.
"We've made a concerted effort to focus on violent crime," she said.
Police Chief Anthony Batts handed down that operational shift, Joshi said, after a poll of the public found residents wanted police to concentrate on violent crime, gang violence and responding to emergency calls.
