CHILHOWIE, Va. -

The Smyth County, Virginia Sheriff's Office has released the names of the victims killed in Sunday's train accident.

They are identified as Louis Perry, 52, of Chilhowie, and Perry's granddaughter, Nevaeh Fields, 6, of Abingdon.

Perry and Fields died at the scene.

The train accident happened off Exit 35 on Railroad Avenue in Chilhowie, Virginia.

Robin Chapman, from Norfolk Southern Railway, confirmed two people died and a boy disappeared after the train hit the group as they were fishing on a railroad bridge Sunday afternoon. The train pumped its emergency brakes and sounded its horn.

Perry and Fields tried to move, but there was not enough clearance and they were hit by the train.

After hours of searching, the boy was found in a field, according to the Smyth County Sheriff's Office. A press release says a search team found a pair of blue jeans near a fence about 400 feet from the incident. From there, they followed a trail through a tunnel under I-81 and found the boy.

The boy told investigators he laid down and hung onto the railroad ties on the edge of the trestle while the train passed over, according to a press release from the Smyth County Sheriff's Office.

He also told investigators he was headed to his grandfather's residence, the only place he knew to go. He was taken to Johnston Memorial Hospital for observation and was released the same day.

His name has not been released.
