CHARLOTTESVILLE, Va. (AP) - A Virginia grand jury alleges that a trash truck driver was under the influence when he collided with a train carrying Republican congressmen in January, leaving one person dead.

The Albemarle County Police Department said in a statement Friday that 31-year-old Dana W. Naylor Jr. was indicted on one count of involuntary manslaughter and one count of maiming another while driving under the influence. It's not clear what the alleged intoxicant was.

Court records don't list an attorney who could comment on Naylor's behalf.
