Actor Gene Hackman, his wife Betsy Arakawa, and their dog were found dead in their Santa Fe home, in a scene that one detective had deemed “suspicious enough in nature to require a thorough search and investigation.

The Santa Fe County sheriff said the actor’s pacemaker was inspected and last showed activity nine days before his and his wife’s bodies were found.

The two apparently had been dead for days or even a couple of weeks when investigators found their bodies while searching the couple’s Santa Fe home on Wednesday.
