There were no signs of obvious blunt-force trauma, carbon monoxide poisoning or forced entry into the home, according to a search warrant filed in the Santa Fe Magistrate Court.

While one dog was found dead inside the home, there were two other dogs running around the property and Hackman’s and wife Betsy Arakawa’s bodies showed signs that they had fallen down abruptly, the warrant stated.

Their bodies were discovered in Santa Fe on Wednesday afternoon during a welfare check, officials said. A neighbourhood security official was able to see the two lying unresponsive on the ground, according to the Santa Fe County Sheriff’s Office.

Deputies with the Sheriff’s Office discovered Hackman, 95, Arakawa, 64, and the dog shortly before 2pm. Hackman’s and Arakawa’s bodies were found in separate rooms of the house on Old Sunset Trail in Santa Fe, the office announced in a news release.
