Investigators looking in to the death of Hollywood actor Gene Hackman and his wife Betsy Arakawa have explained how they think the couple's dog Zinna came to die. This is while the other two dogs owned by the celebrity couple were found to still be alive, despite their owners having died up to two weeks before their bodies were discovered.

The death of Gene Hackman and wife Betsy Arakawa’s dog is still under investigation, officials said Friday as they revealed the doomed pooch had undergone a medical procedure shortly before she died.

Authorities misidentified a deceased dog while investigating the deaths of actor Gene Hackman and his wife, pianist Betsy Arakawa, according to a pet care specialist.
