Zachariah Dobler will spend 48 years in prison for killing a tow truck driver in a DUI accident last summer.

Dobler, 28, was sentenced April 11 after pleading guilty to one count of vehicular homicide and one count of leaving the scene of an accident involving death. He hit 41-year-old Alan Dilley with his car in July 2011, then fled the scene. He was given the maximum sentence.

When the accident occurred, Dilley, a tow-truck driver for Connolly’s Towing, was working on an accident scene where a DUI collision had taken place at West 58th Avenue and Wadsworth Boulevard.

According to a release from the Jefferson County District Attorney’s office, the accident area was lit with flashing lights and emergency vehicles were on scene when Dobler drove his SUV through the coned-off accident scene. He then struck Dilley with his car, throwing him 120 feet.

Dobler did not stop after the accident and was arrested by nearby Arvada police officers just a few blocks away.

Dilley died from his injuries a short time later at St. Anthony’s Hospital. Court records show that Dobler had a previous record, including several prior DUI arrests and a burglary conviction.
