Newhall incident

The Newhall incident, also called the Newhall massacre, was a deadly shootout on April 5–6, 1970, in Valencia, California, United States, between two heavily armed criminals and four officers of the California Highway Patrol (CHP).

Both Alleyn and Pence suffered fatal injuries, while the witness ran out of ammunition and took cover in a ditch. A third CHP patrol car arrived on scene, and the officers briefly exchanged gunfire with the perpetrators, who then fled. Davis stole a car and attempted to flee the area but was spotted by police and arrested. Meanwhile, Twinning broke into a house, taking the occupant hostage.
