Christ Edward Kneubuehl, 56, of Kenosha, was killed during the robbery, although his exact cause of death was not released.
Kneubuehl, a contractor, and three other men were working on a remodeling project at the store when two masked individuals entered the building at around 3 a.m.
The victim's family told TODAY'S TMJ4 Thursday that the robbers stood by him while he died slowly of a heart attack as his stepson watched.
