Their deaths seemed a mystery when maintenance workers called police after spotting the couple through a window on Feb. 26. Arakawa’s body was found in a bathroom and showed decomposition. The Oscar-winning actor was found in a mudroom with his cane. Their dog Zinna was found dead in a kennel. Their two dogs Nikita and Bear were found roaming the property and the front door was open. Officials ruled out an early theory of carbon monoxide poisoning as they investigated.

On Friday, New Mexico’s chief medical examiner shared how the couple died.
