Richard Tkacik's family is suing the Conemaugh Memorial Medical Center and a Richland Township funeral home over the mix-up last year.
The Tribune-Democrat of Johnstown reported Sunday that Richard Tkacik died at the hospital Nov. 23. Two days later, another man's body was at the viewing.
The lawsuit says the mistake was only confirmed when officials at Harris Funeral Home checked the body for a tattoo that Tkacik should have had. His body was eventually located at the hospital.
Funeral home owner William Harris declined to discuss how the mistake happened but said the body was not wrongly buried or cremated and the family incurred no related expenses.
The hospital declined comment.
