HERCULES, Calif. (AP) Police were asking for the public's help after a woman was found dead in her home in the usually quiet city of Hercules.
Neighbors found the body of Susie Ko, 55, on Friday night after her husband called a neighbor to check on her when she had failed to pick him up at Oakland International Airport, police said.
The family's car, a blue 2011 Subaru Outback with an Idaho license plate, was missing from the garage and what appeared to be blood was on the floor near her body, police said. Ko had also suffered a traumatic injury to her head, police said.
Investigators have not determined a motive, and no suspect information has been released.
Homicides and violent crime are uncommon in Hercules, a mostly residential community of upscale homes and quiet neighborhoods on San Pablo Bay, about 23 miles northeast of San Francisco. A resident said the neighborhood is so friendly that everybody "knows each other by face"
"I've been living here 15 years, and it's always been peaceful," 29-year-old Nick Singh told the Oakland Tribune.
"I got home after midnight from work, and the coroner was here and tape was everywhere. Freaks you out a bit," he said.
Police did not immediately return calls or respond to emails from The Associated Press.
