The investigation into the mysterious deaths of beloved actor Gene Hackman and his wife Betsy Arakawa at their Santa Fe, New Mexico, home entered its third day Friday with more looming questions than answers.

This continued investigation seems focused on a specific thread.

Hackman, 95, was found in an entryway after having apparently "suddenly fallen," the affidavit said, while Arakawa, 65, was discovered on her side in the bathroom, with a kenneled German shepherd dead nearby in a bathroom closet.
