Five families, whose sons have been reported missing, including one who lived in the Mission District, want city officials to consider making May 21 a day to remember missing persons in San Francisco.

On Saturday, the relatives gathered for a vigil at Golden Gate Park’s Music Concourse to bring renewed attention to their children’s cases.

“We can’t find them unless people know they’re missing,” Lynn Ching, mother of Sean Sidi, who disappeared on May 21, said to the audience of 200.

The parents of the “California Five,” as the missing men are called, spoke to the crowd between sets of blues. The vigil was designed to draw in passersby to increase awareness.

Shawn Dickerson, 24, disappeared Dec. 2, 2011. He lived in the Mission and has not been seen since he left for work that morning.

Jackson Miller, now 23, of Cupertino, disappeared May 15, 2010. Miller left his car, identification and wallet at the Golden Gate Bridge parking lot. There have been sightings of Jackson in San Francisco, according to his parents. Before he went missing, his parents said Miller had been transitioning from one type of anti-anxiety medication to another.

Cameron Remmer, now 31, of Carlsbad, Calif., disappeared Oct. 6, 2011 while visiting San Francisco. He was reported found by the San Francisco Police Department on Halloween of that year but it was a case of mistaken identity. There have not been any sightings of Remmer since, according to the parents.

Crishtian Hughes, 20, went missing Feb. 7, 2013 while visiting a friend in San Francisco’s Ingleside neighborhood.

Sean Sidi, 19, of the Bernal Heights neighborhood, went missing May 21, 2013. Sidi had suffered a traumatic brain injury earlier this year. His parents said he’s at serious risk. If found, the authorities will know to provide him urgent medical care.

May 21, A Day to Remember Those Missing

The day after Sean Sidi didn’t come home, Lynn Ching, a lawyer, called her friend Elizabeth Prehn, a law student, for help. Prehn, 36, has been involved in many ways, particularly working with the John Burton Foundation for Children Without Homes, a San Francisco-based organization that advocates for California’s foster, former foster and homeless youth, to create a resolution to put before the Board of Supervisors.

“The resolution will make May 21 a day to remember the missing in order to raise awareness of their plight, the impact these missing have on the lives of San Francisco residents, their families and history,” Prehn said.

Prehn has been working with District 9 Supervisor David Campos’ office to bring the resolution forward and requested that the public ask their supervisors to support it.

Adults Hard to Find

“More and more I realized that there are a lot missing people that are missing and they are in plain sight,” Prehn said. “San Francisco has a rich history with these people.”

According to the National Crime Information Center, at the end of August, there were 1,376 active missing person cases in San Francisco and 20,098 active missing person cases in California.

“Because they’re over 18, it’s unclear if they want to be voluntarily missing or not,” Prehn said. “There’s no resources unless there is foul play suspected or an urgent medical condition.”

There has been much frustration for the families.

Trisha Brucker, Dickerson’s mother, said San Francisco police treated her son’s case like a missing wallet.

The police wouldn’t trace Dickerson’s phone, nor check for use of his social security number, according to Brucker. “We must treat all our adults, male or female, like they’re more than a wallet,” she said.
