Authorities have identified a California woman whose body was found in an SUV stopped after a high-speed chase in South Dakota as the mother of the driver.
Attorney General Marty Jackley's office said Thursday the body of 58-year-old Michelle Walsh was found in the rear of the vehicle after a chase with her son, 30-year-old Tosten Walsh Lommen, of California.
Lommen faces charges including aggravated eluding and drunken driving.
Jackley says South Dakota authorities are working with California officials on the death investigation. Autopsy results are pending.
Jackley's office says a state trooper on Monday observed Lommen driving over 100 mph on I-90 in western South Dakota.
Authorities say the vehicle he was driving eventually came to rest in a ditch after officials used spike strips, and Lommen was arrested.
