Gene Hackman, wife and dog found dead in home

An investigation is underway after actor Gene Hackman, 95, and his wife, Betsy Arakawa, 65, were mysteriously found dead alongside a dog in their Santa Fe, New Mexico, home, authorities said.

The couple was found on Wednesday during a welfare check, according to the Santa Fe County Sheriff's Office.

There were no obvious signs of how they died. However, their deaths were "suspicious enough in nature to require a thorough search and investigation" due to all of the "circumstances surrounding" the scene, according to the search warrant affidavit
