(Salem, OR) -- A Salem man has pleaded guilty to a murder discovered almost a year ago. Ashley Jean Gandalfi was killed last January. Her body was discovered inside her own car, following a crash. The driver was Tyler Holman. An autopsy later determined Gandalfi died of a gunshot wound unrelated to the traffic crash. Holman agreed to plead guilty to one count of second degree murder in exchange for other charges being dropped. He'll be sentenced in Marion County court next week, and faces a mandatory minimum of 25 years in prison.
