90-year-old’s adopted daughter sought after slaying

The adopted daughter of a slain 90-year-old woman in El Cerrito is being considered a suspect in her murder and police Wednesday¬†asked for the public’s help in finding her.

El Cerrito police said 50-year-old Alicia Osibin is being considered a suspect in a murder based on concealed human remains that were found in her former residence on Dec. 2, police said.

Police on Nov. 27 initially began investigating reports that the victim, identified as Mary Osibin, was missing.

The investigation led to a home in the 1000 block of Leneve Place, where a search done by various local law enforcement agencies yielded the discovery of human remains stored in a garbage barrel in the garage, police said.

An autopsy conducted by the Contra Costa County coroner’s office determined that the remains were Mary Osibin’s and the cause of her death was gunshot wounds, according to police.

Investigators believe the crime occurred several months ago, police said.

Alicia Osibin formerly resided in the home where the remains were found, according to police. She hasn’t been seen since August and police are uncertain of her current whereabouts.

She made comments to neighbors about traveling to Arizona or Southern California before her disappearance, police said.

Police describe her as a heavy-set woman that stands at 5 feet 8 inches tall. She is known to dress in traditionally masculine attire, police said.

She previously worked in the cleaning industry and may be still working in that capacity, police said. She is also known to use rented vehicles.

Police are asking the public to not to approach the suspect, as she could be armed.

Anyone who sees her or has information about her whereabouts is instead asked to call El Cerrito police at (510) 215-4400 or (510) 233-1234 after hours.
