An investigation is underway after actor Gene Hackman, 95, and his wife, Betsy Arakawa, 64, were mysteriously found dead alongside a dog in their Santa Fe, New Mexico, home, authorities said. The couple was found Wednesday afternoon during a welfare check after their neighbor called and was concerned about their well-being,

The Santa Fe County Sheriff's office initially said it did not believe "foul play was a factor," but a later search warrant affidavit ruled their deaths as "suspicious" amid an ongoing investigation.
