The investigation into the deaths of legendary actor Gene Hackman, his wife, Betsy Arakawa and one of their three dogs, remains ongoing after they were found dead on Feb. 26.Many questions remain about regarding the circumstances surrounding their deaths, but earlier this week, the Santa Fe County Sheriff’s Office issued an update based on the New Mexico Gas Company’s “extensive investigation for gas leaks and carbon monoxide at Gene Hackman’s home,” ruling out one cause of death.

There were no significant findings. NMGC did issue five (5) red tags. One red tag was for a minuscule leak (0.33% gas in air – not a lethal amount) at one of the stove burners,” the statement read. “The other four red tags were for code enforcement violations -not involving gas leaks or carbon monoxide – involving a water heater and gas log lighters installed in three fireplaces.”While a gas leak appears to have been ruled out, three more causes of death were posited by James Gill, Chief Medical Examiner, with the Connecticut Office of the Chief Medical Examiner. Gill is not investigating Hackman’s death in his professional capacity, but he believes both died from natural causes.
