NBC11 from California reports that the plaque, honoring the memory of Armenian Genocide victims, of the famous Mt. Davidson Cross in San Francsco has been stolen in an act of a possible hate crime. Turkish ultranationalists in action?

A 160-pound, 3-by-4-foot bronze plaque that sat at the foot of San Francisco’s Mt. Davidson Cross has been stolen, San Francisco Police Captain Dennis O’Leary said Friday.

The giant plaque commemorated the Armenian Genocide perpetrated by the Turkish government from 1915 to 1918.

It was bolted to a concrete base.

“This is a very serious matter,” said O’Leary. “We are considering all possibilities.”

O’Leary said investigators were also considering the recycling value of the bronze plaque as a motive for the theft.

The department sent out a message and photos to all the metal recycling plants in the Bay Area, and an additional flier to police departments throughout California, O’Leary said.

The 103-foot Mt. Davidson Cross was built and inaugurated by President Franklin D. Roosevelt in 1934.

In 1997, the people of San Francisco voted to approve the sale of the cross to the Council of Armenian-American Organizations of Northern California to preserve the structure as an historic landmark.
