ROME — The body of a teenage Wisconsin student who disappeared shortly after he arrived for an exchange program was found in the Tiber River on Monday, and his death is being investigated as a murder.

John Cabot University confirmed that the body was that of Beau Solomon, 19, who was last seen by his friends in the early hours of Friday morning at a pub in Rome.

‘‘We express our most heartfelt condolences to the Solomon family and to all those who loved Beau,’’ said a statement from the Rome-based English-language university.

Solomon had just completed his first year as a personal finance major at the University of Wisconsin Madison.

An earlier statement from the university said it was ‘‘alerted by his roommate, who reported that he had lost contact with Beau around 1 a.m. . . . and was worried when he did not see Beau at orientation’’ Friday morning.

Cole Solomon, Beau Solomon’s 23-year-old brother, told the Milwaukee Journal Sentinel on Monday that investigators are treating the incident as a murder.
