Police continue to investigate the "suspicious" deaths of actor Gene Hackman, his wife, and his dog. 

As the investigation continues, police continue to release new details about their findings.

One of the latest updates comes from the New York Post. According to the outlet, police have seized medications and cellphones from Hackman's New Mexico residence.

There is also a new update about the potential cause of death.

Police take several items from the scene

The Post, in its report, details all of the things that police investigators have taken from the Hackman residence.

Per the outlet:

Sheriff’s deputies seized the green phones along with Tylenol, a thyroid medication and Diltiazem, which is used to treat high blood pressure, according to the search warrant’s inventory list released on Friday. Medical records from MyQuest, a patient portal from Quest Diagnostics, and a 2025 planner were also taken.

Hackman, his wife, and his dog were found dead on Wednesday by maintenance workers at their multi-million dollar mansion in Santa Fe.

According to police, Hackman's body showed signs of having "suddenly fallen." But, the cause of death remains unclear.

Police have ruled the deaths "suspicious," yet they do not believe that there was any foul play.

Not carbon monoxide?

Oftentimes, when a family is found dead like this, the first thought is carbon monoxide poisoning. It is a silent killer that has been known to lead to the deaths of unsuspecting families.

It now appears, however, that carbon monoxide is not to blame for the deaths of Hackman, his wife, and his dog.

Fox News reports, "Gene Hackman and his wife, classical pianist Betsy Arakawa, tested negative for carbon monoxide, according to the Santa Fe Sheriff's Department."

The big question now, of course, is if not carbon monoxide then what? The answer remains unclear. Fox reports:

And the Oscar-winning actor likely died about nine days before his body was discovered by authorities. During a news conference Friday, Santa Fe County Sheriff Adan Mendoza confirmed the last event noted on Hackman's pacemaker was Feb. 17. When asked if Feb. 17 — nine days before his body was found — could be the day Hackman died, Mendoza noted that was a "very good assumption."

Police, according to Mendoza, are currently analyzing "cellphone data, phone calls, text messages, events, photos in the cell phone to try to piece the timeline together" in order to try to determine what exactly led to death of Hackman, his wife, and his dog.
