In the video, investigators also found a deceased dog and heard a third barking elsewhere on the Hackmans' New Mexico property.

Authorities on Tuesday released a lengthy investigation report detailing some of the last emails, phone calls and internet searches by Gene Hackman’s wife in the days before her death, indicating that she was scouring for information on flu-like symptoms and breathing techniques.

The Oscar-winning actor and his wife, Betsy Arakawa, both died of natural causes about a week apart in February.
