MILWAUKEE (CBS 58) -- The family of a young man killed in a workplace accident is speaking out. 

Twenty-four-year-old Cody Stelzel died Thursday, May 28, after investigators say a boat tipped over and pinned him while he was working at CenterPointe Marine in Milwaukee.

"Cody could walk in every room with his smile and light it up," said Kevin Stelzel, Cody's father. 

OSHA is investigating the incident, but the family says they still don't know what caused the boat to fall. 

His family says his "giving spirit" lives on through organ donation and hopes to one day meet the people he helped save.

Right now, they say what they need the most is closure. 

"We want help. We want everybody out there to help to try to get us some answers and to not allow this to happen to any other family because the hole in your heart is never going to be replaced," said Angela Best, Cody's mother. 

CenterPointe Marine called Stelzel an important member of its team who was always smiling and full of enthusiasm. 

A celebration of life is scheduled for June 6th at DJ's Clubhouse and Lounge.

Anyone who wants to honor his memory is welcome to attend.
