Gene Hackman and his wife Betsy Arakawa were found dead at their home last week and now Hollywood actor Randy Quaid has claimed the couple were "murdered".

Gene Hackman has been found dead along with his wife in their New Mexico home. Police found their bodies Wednesday, but investigators believe they may have been dead for some time.

In March last year, a frail-looking Gene Hackman clung onto the arm of his wife as they made their way to a local restaurant. It was the first time the couple had been seen in public for over 20 years.
