The assassination of Union City, California, police chief William Cann occurred on June 11, 1974, at a public meeting in the Decoto neighborhood. The meeting was intended to address community tension, which was related to the April 1974 police shooting of Alberto Terrones, and to the simmering racial tensions between Chicanos who had settled in Decoto when it was an agricultural area of Alameda County, and newly arrived whites who were remodeling the settlement and the schools in their own image.[1][2]
