The deputies commanded Demorest to drop the weapons but he did not comply. They attempted to use a Taser on him but it was ineffective in subduing him. The suspect then charged at the deputies with a knife in each hand and the deputies fired at him.
Demorest died at the scene. The San Bernardino Sheriff's Homicide Detectives were conducting an investigation into the shooting.
