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.

Gene Hackman and his wife, Betsy Arakawa, kept their private lives out of the limelight, but the couple appeared to be happy during their marriage before their lifeless bodies were found at their $4 million mansion.

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