Forensic tests have strengthened police suspicions that a 65-year-old Italian man killed his partner and her son inside a villa in Longos near Aigio, after security logs showed no one else entered or left the home during the attack.

The bodies of the two victims were discovered on Tuesday afternoon in Longos, Aigio.

Authorities are on a manhunt to arrest the perpetrator of the double murder at the campsite in Finikounda, Messinia.
