Oakland police continue to search for a 50-year-old woman who went missing Sunday.

Sandra Coke, 50, was last seen at about 8:30 p.m. Sunday in the 600 block of Aileen Street by her family. She told her daughter she was going to meet somebody who had information about her missing dog.

Coke has been looking for her dog since May -- when someone broke into her home, stole the dog and then attempted to get Coke to pay for the dog's safe return.

But the dog is still missing. And now, Coke has vanished.

"All we know is my sister is missing and we suspect foul play because this is unlike her," said Coke's sister, Tanya Coke.

Police spokeswoman Officer Johnna Watson said Coke's Mini Cooper was found at about 7:45 p.m. Monday parked in the 800 block of 32nd Street, about two miles from where she was last seen.

Coke serves as a death penalty appeals investigator for the Office of the Federal Defender in Sacramento.

Investigators are continuing to look for Coke and are asking for the public's help in finding her.

She is described as black, 5 feet 6 inches tall and 150 pounds, with a medium complexion, brown hair and brown eyes. She was wearing a black-and-white shirt and dark jeans when she disappeared.

Police said Coke is healthy and has no history of going missing. Anyone who may have seen Coke is asked to call the Police Department's missing persons unit at 510-238-3641, Crime Stoppers of Oakland at 510-777-8672, or the tip line at 510-777-2805.
