Suspect in Fatal 2019 DUI Crash Faces 15 Years in Prison

Chelsea Annmarie Stiles, 27, was convicted of vehicular manslaughter in a DUI crash that left an elderly man dead in 2019 in San Luis Obispo, California. This week, District Attorney Dan Dow announced that Stiles has been sentenced to  serve 15 years and eight months in state prison.

In December 2020, the San Louis Obispo County jury convicted Stiles of numerous offenses. However, after several days of deliberation, the jury was initially unable to reach an unanimous verdict on the most serious charge—murder. Stiles was convicted of  the following felonies: gross vehicular manslaughter while intoxicated, driving under the influence of a drug causing death, four counts of assault with a deadly weapon using an automobile, fleeing the scene of a vehicle collision causing injury, child abuse, and a misdemeanor possession of cocaine.

The deadly crash sequence occurred on December 1, 2019 at approximately 6:00 p.m. on Highway 227. According to investigative reports, Stiles, while under the influence of cocaine, seemingly lost control of her vehicle and rear-ended an automobile carrying a family of four at over 70 miles per hour, disabling the vehicle as a result. Moments later, Stiles inexplicably drove into the opposite lane and struck a 77-year-old San Luis Obispo man identified as Terry Tilton head on at 68 miles per hour. Unfortunately, the impact of collision was severe and killed Tilton instantly. Stiles’s 18-month old daughter and her two dogs were also in her vehicle at the time of both collisions.

Stiles suffered from moderate injuries and was taken to a nearby hospital for medical treatment along with her young daughter who thankfully only sustained minor injuries.

During trial, court testimonies suggested that prior to the deadly crash, Stiles cut her daughter’s scheduled visitation with the father short. The father told investigators that Stiles’ strangely aggressive behavior lead him to believe that she was under the influence of drugs.

A CHP officer Trevor Ashton testified that Stiles was generally incoherent as she was being transported into the ambulance. At the hospital, Stiles admitted to intentionally crashing her vehicle into the two cars she hit but gave no explanation as to why.
