El Cerrito Police Seek Help from Public to Locate Murder Suspect


On Friday, November 27, 2015, the El Cerrito Police Department began an investigation into a report of a missing person, Mary Osibin (90 years of age). The investigation led to a house in the 1000 block of Leneve Place, on December 2.

El Cerrito Police Investigators, assisted by Criminalists from the Contra Costa County Sheriff’s Department and Inspectors from the Contra Costa County District Attorney’s Office, searched the house and located concealed human remains.

The Contra Costa County Coroner’s Office conducted an autopsy, determined that the cause of the death was homicide and confirmed that the remains were those of Mary Osibin. As a result, investigators obtained a warrant for the arrest of Alicia Osibin (7-20-65) for the murder of Mary Osibin. Detectives believe the crime occurred several months ago.

Alicia Osibin is a former resident of the house. Osibin’s current whereabouts are unknown and the El Cerrito Police Department is asking the public for help in locating her. Osibin made statements to neighbors that she might be traveling to Arizona or Southern California. Police believe that Osibin is in possession of a firearm and the public should use caution around her.

Alicia Osibin is described as a heavy set, multiracial female, approximately 5’08” tall. Osibin is known to rent vehicles from rental companies for several months at a time. Osibin previously worked in the cleaning industry and may be currently employed in that capacity. She was last seen in August 2015, in El Cerrito, CA. Osibin has been known to dress in attire that appears more traditionally masculine.

Anyone with information on Osibin’s whereabouts is urged to call the El Cerrito Police Department at 510-215-4400 during normal business hours or at (510) 233-1234 after hours. Information can also be sent by email to [email protected] or by using the El Cerrito Police app, available for download through Apple and Android stores.
