Oregon state Police have arrested a woman who was involved in the crash that killed Chelsea Duffy, 22, of Myrtle Creek.
Troopers arrested Valorie K. Carrigan, 36, at a Philomath area house after she was indicted by a grand jury.
Carrigan is being charged with first degree manslaughter, second degree assault and failure to perform the duties of a driver.
Authorities say that in September of 2012, Carrigan was driving eastbound on Highway 34 near Corvallis. They say Carrigan tried to change lanes in front of Duffy's vehicle and struck the right front section of Duffy's car, causing it to lose control.
Duffy's car went into the oncoming lane and collided head-on with another vehicle.
Duffy was pronounced deceased at the scene and the driver of the other vehicle, Larry Dodge, 52, of Shedd, was seriously injured.
Carrigan was lodged in the Linn County Jail.
