OAKLAND — A 30-year-old woman helping clean up outside an East Oakland home where a child’s birthday party had been held earlier was shot to death Sunday morning, police said.

Less than an hour earlier a 30-year-old man was fatally shot near his home not far from Kaiser Hospital.

The woman killed was identified by police as Lakeya Venson, of Oakland.

She was shot about 1:04 a.m. Sunday outside a relative’s home in the 9200 block of Sunnyside Street. She died later at a hospital.

Police said she had attended a birthday party at the home Saturday for a child. The party had ended Saturday night but relatives and friends including Venson had stayed to socialize and help clean up, police said. Venson and some other adults were outside when a man on the street began shooting toward them before fleeing in a car, Officer Phong Tran said. Venson was the only one hit by the gunfire.

Some bullets did go into the house but no one else was hurt, police said.

Police have not determined a motive yet and said no arrests have been made.

In the other killing, a 30-year-old man was shot to death about 12:15 a.m. Sunday in the 3000 block of Richmond Boulevard.

He was later identified as Brian Bole.

Sgt. Leo Sanchez said Bole lived in the area and may have been walking home from another location when he was confronted and shot. He was pronounced dead at the scene by paramedics.

Sanchez said police are trying to determine a motive. No arrests have been made.

The two killings brought to 16 the number of homicides investigated by Oakland police this year. Last year at this time Oakland police had investigated 24 homicides.
