Former Las Vegas Raiders wide receiver Henry Ruggs III was driving 156 mph with a blood alcohol content twice Nevada’s legal limit before his car slammed into the rear of a vehicle that burned, killing a 23-year-old woman, according to prosecutors.

Ruggs, 22, remained seated in a wheelchair with a foam brace on his neck and jail guards at his elbows during his initial court appearance Wednesday on pending felony charges of driving under the influence of alcohol resulting in death and reckless driving.

Las Vegas Justice of the Peace Joe M. Bonaventure said he was troubled by his initial review of the case against Ruggs, adding that in 16 years on the bench he had never heard of a crash involving a vehicle traveling so fast.
