Overview

• Umberto Efeso surrendered to Carabinieri in Ceparana about an hour after fatally stabbing his ex-partner, Tiziana Vinci, in Bolano on August 13.
• During his interrogation before prosecutor Claudia Merlino, Efeso invoked his right to remain silent and was charged with aggravated voluntary homicide.
• Investigators recovered the folding knife used in the attack but could not locate Efeso’s ankle monitor or the signaling device issued to Vinci.
• Merlino has launched a separate probe to establish why the GPS ankle bracelet stopped working for around ten days despite a report to Fastweb.
• Convalida of Efeso’s arrest and the victim’s autopsy are scheduled as authorities probe potential negligence by those responsible for device maintenance.
