The parents of the 19-year-old University of Wisconsin student who died in Rome last year filed a federal civil lawsuit against the university where their son was about to take classes there for failing to warn him about recent deaths of young adults that occurred near the campus.

Beau Solomon, who had just completed his freshman year at UW-Madison, drowned in the Tiber River after he was robbed and assaulted hours after arriving in Rome on June 30, 2016 to take summer classes at John Cabot University. His death was reported around the world and drew the attention of Pope Francis, who met with Solomon’s parents at the Vatican during a private meeting days after Solomon’s death.

The lawsuit’s complaint, filed Monday by Nick and Jodi Solomon of Spring Green, claims that John Cabot University was negligent and acted with reckless indifference when it failed to warn their son, or anyone from UW-Madison, that four young adults had died of suspicious circumstances within 350 yards of the campus between 2014-15.

One of the young adults was a student attending John Cabot from the University of Iowa, who, like Solomon, died after he was robbed during his first night in Rome. His body was found near the Tiber River.

“The Solomon family is contending that when foreign universities recruit our students to study abroad under their wing, they have a duty to warn them of known criminal elements and prior deaths that are occuring right next to their campus,” Solomon family attorney Bob Gingras said.

John Cabot University, a limited liability company incorporated in Delaware, is a four-year liberal arts university with campuses in Rome that offers undergraduate degrees and study abroad programs to English-speaking students from around the world.

The Solomons, who are seeking punitive and compensatory damages, included John Cabot’s insurer, Chubb Group of Insurance Companies, as a defendant in the lawsuit.

According to the lawsuit’s complaint:

After the student from Iowa died in January 2015 and a yellow orientation bracelet identifying him as a John Cabot student was found on his wrist, a John Cabot employee questioned whether the school should continue recruiting American students because they were “targets.” But university president Franco Pavoncello dismissed talk of doing more to prepare American students, saying that Americans need to learn to take care of themselves.

Back in Iowa City, University of Iowa officials discussed suspending its program with John Cabot because the area around the campus had become too dangerous. It ended its program with the school after it learned of Solomon’s death.

Hours before Solomon died, a John Cabot staff member who drove Solomon and two other UW-Madison students from the Rome airport to their campus residences offered them some advice if they ever got lost in Rome: Follow the Tiber River and it will get you back back to campus. The staff member did not mention that the area along the river was extremely dangerous and where the four young adults had died of suspicious circumstances during the previous two years.

After Solomon attended a welcome reception that evening where nobody from the school warned students that the area around campus was dangerous, Solomon left the campus with some other students. He visited the same establishment the Iowa student had visited before he died. He also was wearing two bracelets: the yellow orientation bracelet identifying him as a John Cabot student and one with the inscription, “USA.”

Later, Solomon was walking along the Tiber River when he was attacked. He suffered two head wounds but was conscious before he was forcefully shoved into the river. His body was found three miles downstream on July 4.

Since Solomon’s death, John Cabot hired a guard to stand at the campus entrance with a loaded gun. It also implemented a curfew and ordered students to attend a safety session during their first day in Rome where the focus is on how “the first few days (in Rome) are especially dangerous,” according to a John Cabot employee. Organized nightly events are held for students during their first days in Rome.

A homeless man, Massimo Galioto, was jailed on an initial charge of manslaughter in connection with Solomon’s death after Galioto’s then-girlfriend, Alessia Pennacchioli, told police she saw Galioto push Solomon into the river after the two men had argued. Galioto was released in early December by a Rome magistrate after Pennacchioli offered uneven testimony during a court hearing, according to Rome newspaper reports.

There are no other suspects but Italy’s mobile and scientific police teams remain assigned to the case, Rome police official Monteleone Marcello said in May.
