A 24-year-old Indiana County man died yesterday and teen-age girl was seriously injured after he crashed his all-terrain vehicle into a utility pole in Shelocta, Pennsylvania State Police said.

Ryan Dixson Henry, of Indiana, was driving around the borough at around 1:25 this morning with a 15-year-old passenger when he drove off the road near 3rd and Main streets. Police said he first struck a newspaper box and then a utility pole, causing both he and the girl to be thrown from the vehicle. Neither was wearing a helmet.

Mr. Henry was taken by ambulance to Indiana Regional Medical Center, where he was pronounced dead at 2:23 a.m. yesterday. He died of head and chest injuries, the Indiana County Coroner Michael A. Baker said.

The girl, who was not identified, was flown by helicopter to Allegheny General Hospital, where she was in serious condition.
