A man was arrested Tuesday after killing his wife and daughter at Cisterna di Latina south of Rome.
The bodies of the two, according to initial information, were found in a house in the San Valentino district.
The police and 118 were on the scene.
The man suspected of the double murder was reportedly detained in Latina by agents of the flying squad.
Latina is a city of around 100,000 people founded in 1932 by Mussolini in the reclaimed Pontine Marshes.
It is one of Lazio's three provincial capitals along with Rome and Rieti.
Cisterna di Latina, the site of a major WWII battle, is about 10km nearer Rome than Latina, which is 55km from the capital.
