Robert Todd Harrell, bassist for the rock band 3 Doors Down, has checked himself into a treatment facility after bonding out of jail, his attorney said Wednesday.

Harrell was arrested last weekend for driving under the influence of prescription drugs after  he was involved in a fatal car crash in a Nashville suburb, killing 47-year-old Paul Shoulders, Jr.

The bassist faces charges including vehicular homicide by intoxication and unlawful possession of a controlled substance.

Harrell is currently out on $100,000 bond. Meanwhile, the band has canceled several upcoming appearances out of respect for the victim.
