In May 1864, Constable F.L. Brill ordered Deputy Andrew Kriss to impound 291 horses owned by Bill Williams, a white Rebel sympathizer and Indian agitator. Deputy Kriss seized the animals from Rancho de las Viejas near present-day One Valley, California. On May 25, as Deputy Kriss was returning to San Diego, two “Californios” (native California Mexicans) ran the horses off. Deputy Kriss pursued the bandits into Mexico, where they killed him. The killers were never apprehended, though the man suspected to have pulled the trigger was identified as Andronica Sepulveda.

An immigrant from Germany, Deputy Kriss had served as a San Diego County Sheriff’s Deputy for only a few years. He was survived by his wife, Rafela, and two daughters, Delphina and Amelia.
