According to the San Mateo County Sheriff's Office, a woman walking down the street in Half Moon Bay with a shotgun and a drink in her hand was fatally shot by sheriff's deputies on Tuesday evening after exchanging fire.

The strange incident on the 800 block of Main Street unfolded around 7:25 p.m., as ABC 7 reports, and the woman is described only as being caucasian and in her 30s or 40s. Deputies say that they demanded she drop the weapon when they arrived on the scene, and she did not comply, and instead fired at them.

The deputies returned fire and shot the woman, who was fatally injured. Life-saving measures were taken, but the woman died at the hospital.

It's not clear how many shots were fired.

As KPIX reports, the deputies involved have been placed on leave as is standard practice after an officer-involved shooting.
