The Hollywood icon, his classical pianist wife and one of their three dogs were all found dead under mysterious circumstances in their Santa Fe, New Mexico, home.

Betsy Arakawa was a classical pianist, creative partner and supportive wife who loved watching DVDs with her husband Gene Hackman.

Santa Fe County Sheriff Adan Mendoza told NBC's “Today” show that investigators were trying to sort out conflicting stories about the doors. He said several doors were unlocked and a rear door was open, which allowed two dogs that survived to go in and out. He also said he thinks the front door was closed but unlocked.
