Dassow was transported to Froedtert Hospital where he was pronounced dead.

The Oak Creek Police Department is investigating along with the Milwaukee County District Attorney's Office and OSHA. The Wisconsin Department of Natural Resources also assisted in the investigation, according to Oak Creek Police.
