Newschannel5.com reports that Harrell's Cadillac clipped a Ford pickup truck at a high rate of speed, which caused the truck to go out of control, strike a guardrail, travel down an embankment and overturn, according to the police department's preliminary investigation.

The driver of the pickup, 47-year-old Paul Howard Shoulders, was not wearing a seatbelt and was ejected from the truck. He was pronounced dead after arriving at Vanderbilt University Medical Center.

Harrell's car reportedly stopped a quarter mile away and struck a retaining wall. Police suspected that Harrell was under the influence and they said that he showed signs of being impaired during field sobriety tests.

Harrell reportedly admitted to drinking hard cider and taking prescription Lortab and Xanax and the Davidson County Sheriff's deputies discovered a plastic bag in his sock during booking which contained Xanax, Oxycodone and Oxymorphone pills.

The musician was charged with vehicular homicide and bringing controlled substances into the jail, according to the report.
