An Arvin Sango employee died Monday night when she was crushed by one of the company’s presses.

Thelma Sue Bailey, 57, of 507 S.R. 156, Florence, was pronounced dead at 10:47 p.m. at Arvin Sango after she was caught in a press, Jefferson County Coroner Alice Jackson said. “I’m not sure how it happened,” Jackson said.

An autopsy this morning found that Bailey died of massive chest and abdominal injuries, Jackson said.

A toxicology test will be performed as part of the standard procedure, Jackson said. The results of the test will not be available for several weeks, she said.

Tim Grogg, deputy commissioner of legal affairs and media relations for the Indiana Occupational Safety and Health Division, said the division is aware of the fatality at Arvin Sango, 2905 Wilson Ave., but it had not had the opportunity to investigate as of this morning.

“We have not had investigators on the scene,” Grogg said. All IOSHA knows is that “ the lady was somehow caught in a machine.”

Grogg said IOSHA investigators will visit Arvin Sango today.

IOSHA has only preliminary information, “which is a bit sketchy at this point,” Grogg said. “We don’t have any idea (what happened) until the inspectors get there.”

Lt. John Wallace of the Madison Police Department also is investigating, Jackson said. Wallace was unavailable for comment, as was Dan Baughman, executive vice president and secretary-treasurer of Arvin Sango, which makes automotive assemblies such as fuel tanks and exhaust pipes.
