Sandra Lee Harmon died from her injuries on May 5. 

Two deputies fired shots – but only one had his body camera turned on.

The San Mateo County Sheriff’s office released 12 minutes of video.

This includes footage from a security camera at a Half Moon Bay business showing a woman carrying what appears to be a rifle down Main Street.

A 911 caller tells a dispatcher the woman has a gun, a bottle of wine, and warns a "race war" was going to happen.

What happened next was not recorded.

That’s when a deputy and the 56-year-old Harmon exchanged gunfire outside a motor home.

A second deputy arrived with body-worn camera activated.

Both deputies are heard ordering Harmon to the get on the ground.

They opened fire when – according to the sheriff’s office – Harmon reached for her gun that she had either placed or dropped on the ground.

The District Attorney’s office is investigating the shooting.
