He had been reported missing to Berkeley police on Oct. 23, Berkeley Police Officer Jennifer Coats told Patch tonight, Friday.
The release of the man's identity follows a plea from his son, Jeremy Jacob, on Facebook to help find the missing father.
"Because of the connection to the previous Berkeley case, BPD will be the lead agency regarding this investigation," Coats said.
"The manner and cause of Jacob’s death are still under investigation," she said.
The Oct. 24 plea on Facebook by Jeremy Jacob includes photos of Jacob with a request to repost this notice:
"*PLEASE REPOST*: My Father Jerald Jacob has been missing since yesterday 10.23. He was last seen at the Berkeley Marina wearing a black San Francisco Giants sweater, black cap, blue jeans and brown tennis shoes. He stands 5 ft 9 172 Lbs with a salt and pepper goatee. Plz contact me or the Berkeley Police Department (510) 981-5900 if seen."
A later post on Oct. 28 said his father was at HS Lordships restaurant at the Bekeley Marina on Wednesday.
Police were alerted to a body in the water next to Frontage Road, about half mile south of University Avenue, by a 911 call around 3:30 p.m. Wednesday, said Lt. John King of the East Bay Regional Park District police. The spot is near the Berkeley Marina.
The park district police oversaw the response Wednesday because that section of the shoreline is part of McLaughlin Eastshore State Park, which is overseen by the park district.
