ANCHORAGE -

A Wasilla woman involved in an ATV collision succumbed to her wounds and died early Saturday morning, despite attempts by friends and hospital staff to save her, troopers say.

Alaska State Troopers responded to reports of an ATV collision on Whiskey Gulch beach at 6:21 p.m. on July 4, followed closely by Anchor Point EMS. A woman reported to be the driver was transported from the scene to South Peninsula Hospital for treatment.

Witnesses reported that the woman, identified as 23-year-old Shelby Caven of Wasilla, was returning to the beach and attempted to cross the mouth of the Stariski Creek, when the ATV struck the creek bottom and flipped forward. Craven was seen standing up just after the collision, but collapsed into the water shortly after.

Fellow ATV riders carried Caven to the highway to waiting emergency responders. Another passenger on the ATV, Jaclyne Schacle, 22, was also reported injured during the incident, and was treated for minor injuries.

Caven was transported from SPH to Providence Medical Hospital by Med Flight, where she was later pronounced dead by staff at 3:26 a.m., having suffered from injuries sustained during the initial collision.

Troopers believe alcohol was a factor in the incident, and in their report emphasized the importance of “riding safely using helmets and without intoxicants”.
