The Jackson County Sheriff's Department has released the name of the 17-year-old girl who was driving in a fatal crash that killed her mother.

Shanelle Myrick, of the 1800 block of Kings Highway, Medford, was treated at a hospital and released after the early morning crash Thursday.

Her mother, Deeanna Lee Ruddick, 49, wasn't wearing a seatbelt and died in the rollover crash at about 3:20 a.m.

Myrick was driving a two-door 1988 Toyota north on Sterling Creek Road at about 45 mph when she lost control on a curve, a preliminary investigation indicated.

The vehicle crashed into a dirt embankment and rolled onto its side.

The unposted, basic-rule speed limit in the 600 block of Sterling Creek Road where the crash happened is 55 mph, Jackson County sheriff's Sgt. Dace Cochran said.

Because Myrick was wearing a seatbelt, she escaped serious injury, but Ruddick was thrown into the windshield and died, police said.

The teen will undergo routine drug and alcohol tests, the results of which will take at least two weeks, investigators said. She initially told officers that she and her mom were going to Applegate Lake.

Crash reconstructionists from Ashland and Medford police and the sheriff's department are still investigating.
