The semi-truck driver accused of hitting and killing a Loudon County Sheriff deputy was under the influence at the time of the crash, according to a report from the Tennessee Highway Patrol.

Christopher Savannah, 43, faces several charges following the crash, which occurred on Interstate 75 near the Tennessee River Bridge Thursday morning. Loudon County deputy Sgt. Chris Jenkins was reportedly killed after Savannah failed to slow down after a rolling barricade, which was implemented while Sgt. Jenkins removed debris from the roadway.

According to the report, Savannah struck several cars and Sgt. Jenkins, killing him.

“Sgt. Jenkins with the Loudon County Sheriff’s Office was attempting to remove a ladder from the roadway,” the report said. “Multiple vehicles had slowed due to Sgt. Jenkins conducting a rolling roadblock before stopping on the right shoulder. Vehicle one struck vehicles two and four before striking Sgt. Jenkins.”

Savannah was charged with vehicular homicide by intoxication, vehicular homicide by recklessness, reckless endangerment x2, DUI, simple possession, possession of a handgun under the influence, possession of drug paraphernalia and other traffic charges.

Officials with the THP are leading the investigation.
