POTTER VALLEY, Calif. —  A Mendocino County woman who was trying to kill mice in her trailer with a gun ended up shooting herself and another person.

The 43-year-old woman pulled out her .44-caliber Magnum revolver after she saw the mice scurrying across the floor of her trailer on Highway 20 in Potter Valley, sheriff's officials said.

But she accidentally dropped the gun, which went off as it struck the floor. The bullet went through the woman's kneecap, bounced off the keys sitting on the belt loop of a 42-year-old man in the trailer and grazed the man's groin before ending up in his coin pocket.

Authorities did not release the shooting victims' names.

The mice escaped the shooting unharmed.
