Authorities are continuing their investigation into the circumstances surrounding the death of Academy Award-winning actor Gene Hackman, 95, and his wife, Betsy Arakawa, 64, a classical pianist. The couple were found dead, along with one of their dogs, Wednesday in their home in the southwestern U.S. state of New Mexico.

Santa Fe County Sheriff Adan Mendoza said this particular item “is something of concern" regarding the deaths of the actor and his wife, Betsy Arakawa.

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.
