(ABCNEWS.GO) — A U.S. student studying abroad has been arrested for attempted murder for allegedly stabbing his friend 25 times after a drug-fueled night out in Rome on Halloween.

At an apartment around the corner from Rome’s famous Coliseum, 20-year-old Reid Alexander Schepis, a first-year student at John Cabot University, a private U.S. liberal arts college, allegedly stabbed his longtime friend Fabio Malpeso.

Schepis and 19-year-old Malpeso, friends from New Jersey, were partying late Halloween at a Rome night club. Schepis told authorities he’d used drugs for the first time that night, mixing ecstasy and alcohol.

Schepis told police that he has no memory of what happened after the two headed to the apartment Malpeso shared with his sister to sleep off the wild night, and he allegedly went into his sleeping friend’s room at dawn and repeatedly stabbed him.
