The search for an Oakland woman who disappeared Sunday night is continuing this morning in Vallejo with boats and dogs focusing efforts at a lake near an amusement park.
Solano County sheriff's Lt. Daryl Snedeker told reporters this morning that authorities resumed a search for 50-year-old Sandra Coke in 3-mile area around Lake Chabot, behind Six Flags Discovery Kingdom.
Coke was last seen at her home in the 600 block of Aileen Street around 8:30 p.m. Sunday.
According to family members, she had left to meet someone with information about her family's stolen dog.
When she never returned, her 15-year-old daughter reported her missing. Her daughter was the last person to see Coke.
Oakland police Officer Johnna Watson said Coke was seen Sunday night with Randy Alana, 56 -- a person of interest in her disappearance.
Alana has since been arrested on an unrelated parole violation. He had dated Coke in the past, according to police, and is a registered as a high-risk sex offender.
He has prior convictions for rape, rape in concert with force or violence and kidnapping to commit a sex offense.
Watson said this morning at the search site, "We want to rule out if there is not foul play."
The search also involves looking through surveillance footage, and interviewing family and friends to learn more about Coke, who works as an investigator at the federal public defender's office in Sacramento.
Coke has not gone missing before and it is uncharacteristic of her to leave her daughter alone at home unexpectedly, family members have said.
