— The owner of a dry silicone mold company in southern Indiana is dead at 59, and the company he founded is no more.

Thomas G. Siegel, 57, died Monday after being admitted to a hospital in his hometown of Dyer, about 30 miles south of Indianapolis.

He was not under the influence of drugs or alcohol when he died, and his death was not being treated as suspicious, officials with the Indiana State Police said.

Siegel started the company in 1979, producing dry molds for use in automotive parts and automotive accessories.

He became an investor in the company and served as president, and he ran it for nearly a decade.

The company was based in the Indianapolis suburb of Dyersville, about 60 miles southeast of Indianapolis, and was known for making a range of products, including the popular Airflow molds.

Snyder, a retired police officer who lived in Indianapolis, said Siegel was a longtime family friend and was an avid car collector.

He called him a good man and a good friend, Snyder said in a statement.

A spokeswoman for the Dyer Police Department said there were no additional details at this time.
