A woman died Wednesday in a freak accident in north Casper when a scoring box unexpectedly toppled and crushed her.

Police were called to the Field of Dreams baseball complex at about 5:30 p.m. when a youth baseball player found the woman, whose name was not released, "laying down face down," according to a witness.

"We hustled over there and saw the body laying face down," said Terry Hiatt, a Casper area teacher and baseball parent who was filling in for a team coach when the body was found. "And basically I tried to take a pulse and I couldn't feel anything."

Hiatt said the woman had apparently been crushed when the structure, which some witnesses thought was a shed, blew over in the wind.

"I got over here, and at first I didn't notice the shed was on its top like that," he said. "The kid just wanted to go over and see it, and then he said somebody was laying over there."

Hiatt and another parent did chest compressions until police and paramedics arrived.

According to Casper police Sgt. Richie Randel, the woman was an airline pilot who did not live in the area. A preliminary investigation indicated that she might have been walking or jogging behind the structure about 5:20 p.m. Randel said the woman was wearing workout-type clothes and the structure was "new construction in the area."

The scoring box, which is owned by the Casper Parks Department, somehow dismantled and fell on the woman, but the extent of her injuries will remain unknown until further investigation, said Natrona County Chief Deputy Coroner Gary Hazen.

Officials were working Wednesday evening to identify and notify the woman's next of kin.
