Jesse Warren Ross was 19 and a sophomore at the University of Missouri–Kansas City when he vanished during a November 2006 Model United Nations trip to Chicago. A communications major and a popular on-air personality known as Opie, he attended the conference at the Sheraton Chicago Hotel and Towers while UMKC students were staying at the nearby Four Points Sheraton.

Surveillance shows Jesse leaving the Four Points around 12:43 a.m. on November 21 and arriving at the Sheraton Chicago at 1:09 a.m. He attended a late-night, simulated Security Council meeting and was last seen on camera in the Sheraton lobby about 2:30 a.m., wearing a white t-shirt, a green warm-up jacket, blue jeans, and black athletic shoes. He never returned to his room; his belongings stayed behind and his phone and credit cards were never used.

Searches including divers and canine teams, and review of surveillance footage, produced no trace of Jesse. Investigators noted a side door not covered by cameras could explain the lack of later images. Police have said there is no evidence supporting foul play; family-funded private investigators have pursued leads but none has resolved the case. The disappearance remains an active missing person investigation.

If anyone attended that conference or remembers seeing Jesse that night, please share what you know.
