The violence -- which was stretched over several bloody hours and two counties and sparked a massive police manhunt -- began around 10:30 am when a police deputy went to investigate a suspicious vehicle parked at a hotel in Sacramento.
As he approached, the driver opened fire and struck the deputy in the forehead, Sacramento Sheriff Scott Jones told a news conference.
The deputy, Danny Oliver, a 15-year veteran who was married with two daughters, was killed.

A short time later, they carjacked a vehicle and when the driver resisted, he too was shot in the head, Jones said. His condition was not immediately known.

Somewhere along the way, two more police officers were shot. One of them was killed, authorities told local media.
