On April 5, 1970, four CHP officers were shot dead by two heavily armed career criminals at a Standard Gas Station in present-day Valencia. The shootout was the deadliest attack on law enforcement in California history. As Valencia had barely been developed, it came to be known as the Newhall incident. One of the perpetrators was sentenced to life in prison; the other committed suicide. In the aftermath of the incident, policing was transformed nationwide — police training and weaponry were improved and bullet proof vests became widespread.
