The video shows two men inside an Oakland restaurant. They are with two other men who were found murdered on in Vallejo about an hour after this video was recorded.
Investigators want to identify the men and hope they can shed light on what happened that night. They are not being called suspects; at this point, they are "persons of interest."
If you recognize them, you should call the Solano County Sheriff's Department at (707) 421-7000.
