If convicted, Bostick could be sentenced to at least 30 years in prison.

This isn't Bostick's first-run in with the law in Mississippi. He was convicted of felony drunken driving in March 2009, soon after having been convicted in July 2008 and November 2008 for drunken driving.

The former Internal Revenue Service investigator was one of nearly 200 convicted criminals, including four murderers, whom Gov. Haley Barbour pardoned shortly before leaving office earlier this year. The pardons elicited an uproar, with Attorney General Jim Hood leading a charge to overturn them. But after legal challenges, they were upheld.

Bostick was still going through a court-mandated drug rehab program when he applied for his pardon last summer. On Sept. 30, the Mississippi Parole Board sent its review of Bostick's application to Barbour, recommending a full pardon in a 3-2 vote.

A week later, on Oct. 7, Bostick was driving under the influence again, according to the Mississippi Highway Patrol. Charity Smith attempted to pull out onto a highway just outside Tupelo when Bostick's truck slammed into the side of her car, the patrol says.

Smith was killed, and her older sister suffered serious injuries. Bostick was jailed for violating his probation from his previous DUI cases.

In the grand jury indictment, Bostick is accused of "willfully, unlawfully and feloniously" driving while intoxicated; refusing to immediately stop or give his name, address or registration; and having "negligently" caused Smith's death.
