MOUNT VERNON — A man who says he accidentally shot his girlfriend while they were camping in a tent near Marblemount was charged Wednesday in Mount Vernon with manslaughter.

Thirty-one-year-old Clayton Riggles told investigators he was putting his .45-caliber revolver under his pillow to go to sleep Saturday when it went off and hit 28-year-old Brittany Zika in the head.

The Rockport woman worked as a veterinary assistant at Skagit Animal Clinic in Burlington.
