A man and his wife were shot dead in their apartment building in north Rome on Thursday, police believe by their 82-year-old neighbour who then committed suicide with the same gun.
Police are investigating the double murder which took place outside the couple's ground floor apartment in the Tomba di Nerone district on Rome's northern outskirts.
Police called to the crime scene also found the body of the couple's elderly neighbour inside his apartment, which was nextdoor to theirs.
The couple were in their sixties and the woman was well known in the neighbourhood for feeding stray cats.
