CASPER, Wyo. (AP) — An employee who died at a natural gas processing plant in southwestern Wyoming has been identified as a Kemmerer man.

36-year-old Michael Smuin died at the Williams plant in Opal on Wednesday.

Authorities say a pipe had burst shortly before Smuin, an operator technician, was found dead. He had been doing routine maintenance work at the time.

Officials say his cause of death will be determined by a coroner.

The plant was still shut down as of Thursday morning.

Smuin's death remains under investigation.
