A Tukwila man was sentenced Oct. 30 to nearly 11 years in prison for a multiple-vehicle collision on SR-509 in December 2013 that killed a 54-year-old Marysville woman.

Christopher Wittman, 25, had been drinking alcohol and smoking marijuana and was talking on his cell phone when he crashed his car through a fence and over an embankment onto State Route 509 north of Seattle-Tacoma International Airport, prosecutors said.

His Chevy Malibu landed on top of a Mazda sedan driven by Clay Eakins of Marysville. Eakin’s wife, Barbara, was sitting next to him. She suffered severe head injuries and died Jan. 7 at Harborview Medical Center in Seattle.

Clay Eakin suffered major injuries and was treated at Harborview. The initial crash caused a chain reaction in which several people were injured.

Wittman pleaded guilty in September to charges of vehicular homicide (DUI), vehicular assault (DUI) and reckless endangerment. The standard sentence is nine to just over 12 years. He was sentenced by King County Superior Court Judge John Chun at the Maleng Regional Justice Center in Kent.

The accident occurred at about 5 a.m. on Dec. 18, 2013. Investigators determined Wittman drank at least six shots of hard liquor before the accident, prosecutors said.
