The sudden deaths of Gene Hackman and Betsy Arakawa are under forensic investigation after autopsy findings showed no external injuries. Authorities are conducting toxicology and carbon monoxide tests to determine possible internal causes, including poisoning or environmental hazards.

The couple was found in their Santa Fe home after a welfare check. Investigators noted an unsecured door, scattered pills, and a deceased dog, raising concerns about toxic exposure or an undetected environmental threat.

Forensic experts are focusing on toxicology and environmental tests, with carbon monoxide poisoning as a key possibility. However, initial gas inspections found no leaks, leaving other potential toxic exposures under scrutiny.

This case underscores public safety concerns and the need for forensic advancements. As authorities await lab results, the findings could impact home safety regulations and forensic investigation methods, helping to prevent similar tragedies.
