Suspects identified in UCPD Attempted Murder on a Deputy Investigation 
The suspects in the investigation have been identified as:
MICHAEL DORTHICK, 56 year-old-male from Union City
LIZZETTE CHANN, 54-year-old female from Union City
UCPD obtained search warrants for the location, and, after attempting to establish contact with Dorthick and Chann for several hours, UCPD SWAT operators located both suspects with apparent gunshot wounds and were pronounced deceased.
UCPD Detectives believe these two individuals were responsible for the shooting of the ACSO deputy, and no other suspects or victims were located inside. The preliminary findings of the investigation support evidence that the suspects died as a result of a murder-suicide. This investigation remains active and there is no existing threat to the public at this time.
The UCPD Investigations Unit is actively investigating the incident and anyone with information is encouraged to contact UCPD or your local law enforcement agency. If you wish to remain anonymous, information may be left at 510-675-5207 or at [email protected].
