Hackman and his wife, Betsy Arakawa, 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. Investigators are trying to figure out the last time anyone saw or spoke to them, Santa Fe County Sheriff Adan Mendoza told NBC’s “Today” show on Friday.

Legendary actor Gene Hackman, 95, and wife Betsy Arakawa, 64, and their dog were found dead in their home outside Santa Fe, authorities say.

Authorities say there were no signs of foul play, but the circumstances are “suspicious enough” to warrant a full investigation into the cause of death.
