OAKLAND -- An Amber Alert for a teenage girl police thought was abducted from an Oakland hills supermarket by a suspected shoplifter was canceled Wednesday after investigators found and interviewed the driver of the vehicle and determined that the girl was an adult and had not been kidnapped, authorities said.

Police are still seeking the suspected shoplifter, identified as 54-year-old Roy McCamey, whose last known address was in Oakland. Authorities said they are no longer searching for a red sedan believed to be linked to the incident, which triggered a massive police response Tuesday.

Oakland police Officer Johnna Watson said all three people in the car knew each other and that police don't think a carjacking or kidnapping occurred.

Besides McCamey, police are also still seeking the woman.

McCamey has a history of theft arrests and is known to frequent the area of the Safeway store at 4100 Redwood Road where the shoplifting happened. His name came up as a person of interest after police released store video of a man seen taking lobster and steaks from the store and tips started coming in to investigators.

Police were initially told that the shoplifter threatened store employees with a knife before running out into the store parking lot and getting into a maroon car that was driving by the front entrance. Witnesses told police the occupants of the car were an older black man and a female that appeared to be 13.

Witnesses also told police the occupants of the car yelled they did not know the suspect, prompting a large police response and the issuing of an Amber Alert.

Police were always concerned that nobody reported the pair missing.

But until the driver was located, Watson said, "we have to treat it as a carjacking and kidnapping. We would be negligent if we did not."
