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.

Oscar-winning actor Gene Hackman’s pacemaker shows he probably died on Feb. 17, days before investigators found his body and that of his wife in their New Mexico home.

Authorities said there were no obvious signs of foul play, but that the circumstances of their deaths warranted further investigation.
