A woman who caused a crash that killed Myrtle Creek native Chelsea Duffy in September 2012 east of Corvallis pleaded no contest Tuesday to criminally negligent homicide.
Sentencing for Valorie K. Carrigan of Philomath was set for April 15 in Linn County Circuit Court.
While changing lanes on Highway 34, Carrigan clipped the eastbound vehicle Duffy, 22, was driving. Duffy lost control and was killed when her vehicle collided head-on with a westbound vehicle, seriously injuring the driver.
Duffy graduated from South Umpqua High School in 2008 and was a senior at Oregon State University.
Carrigan, then 36, was initially indicted for first-degree manslaughter.
Defense attorney Stephen Ensor told the Corvallis Gazette-Times that prosecutors will seek a 30-month term, but he will argue for probation.
Carrigan also pleaded no contest to third-degree assault.
