Med student's disappearance baffles police, family

Ambrose Monye, a 28-year-old medical student, is pictured here in a photo provided by the family.

Ambrose Monye purchased his cap and gown and told his family he wanted to be a cardiologist.

But the 28-year-old medical student, weeks away from his graduation, vanished without a trace more than a week ago, and Chicago police say they have no leads in the case.

Monye was last seen around 7 p.m. on April 22, walking toward the University of Chicago's John Crerar Medical Library, where he'd often go to study, according to investigators.

No one has seen or heard from Monye since then -- and the family told Wednesday there has been no activity on his cellphone, credit cards or email since he disappeared.
