Gene Hackman's nephew addresses actor's death theories: report

Circumstances surrounding the death of Gene Hackman and his wife, Betsy Arakawa, remain a mystery to Santa Fe, New Mexico, authorities as they work backwards and piece together evidence to figure out how the couple died.

The late Oscar winner's nephew, Tim Hackman, admitted his family refuses to jump to any conclusions regarding his uncle's death.

New Mexico officials found Hackman, Arakawa and one of their dogs dead in their home one week ago. Detectives described their deaths as "suspicious enough in nature to require a thorough search and investigation," according to a search warrant affidavit obtained by Fox News Digital.

Hackman and Arakawa tested negative for carbon monoxide, Santa Fe County Sheriff Adan Mendoza confirmed at Friday's press conference. Their residence was tested for the colorless, odorless gas and was cleared by the Santa Fe City Fire Department after authorities found no evidence of a carbon monoxide leak or poisoning.

"We’re waiting on toxicology. That will tell us everything," Tim told Us Weekly. "It’s hard to theorize."

Mendoza confirmed the last recorded activity on Hackman's pacemaker occurred on Feb. 17. Authorities assumed this was Hackman's last day alive, as the Oscar winner's body was not discovered for nine more days.

"According to the pathologist, I think that is a very good assumption that that was his last day of life," Mendoza said during a press conference on Friday. 

Officials also revealed that Arakawa's body was found decomposed with bloating on her face and mummification in her hands and feet. Hackman was also found to have the same signs of decomposition as his wife.

Recently, sheriffs confirmed a misstep in the investigation after wrongly identifying the dog found dead in the Hackman home.

The dog that was found dead near Arakawa's body was misidentified by the Santa Fe County Sheriff’s Department in the investigation, Fox News Digital confirmed.

The owner of Santa Fe Tails, the pet care facility that took in Hackman’s two other surviving dogs, explained that the dead dog was a different breed than what is listed in the search warrant affidavit.
