South Lake Tahoe police are asking the public’s help in confirming the identity of a man seen recently in the community who is thought to be an Alameda County man reported missing by his family in 2010.

Police said Jackson Miller, 22, is considered a voluntarily missing adult from Cupertino. Shortly after he went missing in 2010, his car was found in the parking lot of the Golden Gate Bridge in San Francisco. Miller’s wallet and cellphone were found inside the vehicle.

The Golden Gate Bridge Authority confirmed that no one jumped from the bridge the night Miller’s car was parked there, and video surveillance cameras showed Miller leaving his vehicle and walking out of the park area, according to a Police Department news release.

Although the Alameda County Sheriff’s Office has received a number of unconfirmed sightings of Miller in the Bay Area, he has not been seen by his family since his disappearance in 2010. At the time, he was reported to have been anxious and depressed due to medication withdrawal. Given the length of time that he has been missing, Miller’s family has grown increasingly concerned, police said.

This week, a South Lake Tahoe resident called the Police Department after seeing a missing-person poster displaying Jackson Miller’s picture. The caller reported having seen Miller in South Lake Tahoe on a number of occasions, most recently in mid-July. Although the caller seemed confident, police said, the report remains unconfirmed.

Police said no crime is suspected at this time, but they would like to find Miller to confirm whether he is in the area and whether he needs help.

Miller is described as 5 feet 10 inches tall, weighing 160 pounds, with brown hair and blue eyes, and may have facial hair. Police said he is not known to have any financial resources, and his circle of friends is unknown to his family. Additional photos of Miller are posted at www.findjacksonmiller.com.

Anyone who can confirm Miller’s identity and location is asked to call South Lake Tahoe Police Department dispatch at (530) 542-6100, even if the sighting occurred weeks or months ago. Callers also may report information to Lake Tahoe Secret Witness at (530) 541-6800 if they wish to remain anonymous.

The investigation is being handled primarily by the Alameda County Sheriff’s Office, and the case number there is 101350430C. The contact with the Sheriff’s Office is Sgt. Rick Alanis at (408) 686-3664.
