OAKLAND, Calif. (AP) — An extensive search was underway in Northern California Thursday night for a missing federal criminal defense investigator after a parolee was identified as a person of interest in her disappearance, authorities said.
More 50 local, state and federal investigators combing an area around the Solano County Fairgrounds in Vallejo overnight for any clues involving the disappearance of Sandra Coke, Oakland police spokeswoman Officer Johnna Watson said.
Coke, 50, a capital case investigator for the federal public defender’s office in Sacramento, was last seen in Oakland on Sunday.
Police arrested Randy Alana, 56, of Oakland, a registered sex offender, on an unspecified parole violation on Tuesday as he was being questioned about his ties to Coke. Watson said the arrest took place after investigators discovered he was with Coke on Sunday.
“He is a person of interest. We do know they were seen together last Sunday evening,” Watson said. “We are looking at an angle to see if foul play was involved.”
Coke left her Oakland home shortly after 8:30 p.m. Sunday after reportedly telling her 15-year-old daughter she was meeting with someone who found her missing dog.
Coke said she would be back in 30 minutes. Her daughter called police when her mother did not return home that night.
A family friend, Laura Burstein, said Thursday that Coke dated Alana more than 20 years ago. Another friend, Dan Abrahamson, told KGO-TV, that Alana recently reappeared in the Bay Area and reached out to Coke for help.
“All we ask is if he has any information about the whereabouts of Sandra that he immediately come forward with it,” Burstein said.
Alana was being held in jail without bail Thursday. He is considered a high-risk sex offender as state records show he has convictions for rape and kidnapping.
Earlier Thursday, dozens of Coke’s family and friends announced a $100,000 reward for any information leading to her return.
“These last few days have been a living nightmare,” Tanya Coke, her sister, said Thursday. “We are all desperate to see her return home safely.”
Police found Coke’s 2007 Mini Cooper convertible on Monday, just a few blocks from her home and her two cell phones were found near the Oakland-Emeryville border and near Interstate 80 in Richmond.
Oakland Police Lt. Chris Bolton said they are still treating Coke’s disappearance as a missing person’s case. Thursday’s search in Vallejo, about an hour from Oakland, will also include the FBI, California Highway Patrol, and divers from the Alameda County Sheriff’s Department.
Coke’s sister, however, is convinced that foul play is involved.
“We are certain that she has been abducted,” she said. “She would never leave her daughter for more than an hour or two so we know that there must be something terribly wrong.”
Watson said authorities will look into all angles.
“Our primary focus on this investigation is to find Sandra Coke,” Watson said. “We are hopeful that she is safe and we hope to find her safe.”
