A worker at a popular Ohio bowling alley was killed after he was crushed in a freak accident involving a pin-setting machine. An investigation by the Occupational Safety and Health Administration has been launched to determine what happened.

Investigators from OSHA were already at the bowling alley outside of Cleveland Friday, just one day after 53-year-old David Geiger was entangled in a pin-setting machine he was trying to repair, pulling him to his death.

There were reportedly bowlers and other workers at Northwest Lanes at the time but no one saw what happened behind the lanes, according to WCPO-TV. The Butler County coroner ruled that Geiger died of accidental traumatic asphyxia.

"He was sent back for a problem with one of the lanes," Fairfield police spokesman Doug Day told WCPO-TV. "He'd been back there, they tried to call him, and when he didn't answer the call they went back there and they found him."

According to Fairfield Police Chief Michael Dickey, Geiger was likely "trying to release a stuck ball and a piece of clothing got caught on one of the moving parts and essentially pulled him into the mechanism."

Geiger had been an employee of the bowling alley for four years. However, former co-worker Nathan Hursell said that Geiger had been working in bowling alleys for 30 years.

"Dave was a stand-up guy," Hursell told the television station. "He knew exactly what he was doing back there. It's one of those things where you don't think twice of that happening. It's just a common spot that we get in the machines and it's just a freak accident."

It seems that this was simply a terrible accident, according to Cincinnati area director of OSHA Bill Wilkerson.

"Nothing we have seen so far, in the early stages of the investigation, would lead us to believe there will be criminal sanctions."
