Six men from Haiti who were scheduled to attend the Special Olympic USA Games in Orlando, Florida, are missing, according to the Osceola County Sheriff’s Office. 

The men, identified as: Antione Joseph Mithon, 32; Nicholson Fontilus, 20; Peter Mianovich Berlus, 19; Anderson Petit-Frere, 18; Steevenson Jacquet, 24; and Oriol Jean, 18, were last seen in Kissimmee, Florida, around 2:30 p.m. Monday when they turned in the keys to their hotel rooms, the sheriff’s office said. The men left their personal belongings behind.

Authorities said they believe the disappearance is an isolated incident, and no foul play is suspected.

In a statement, the Special Olympics said five of the missing men “are not Special Olympics athletes” and one “is an adult with an intellectual disability.”
