Medical Student Missing for Over 1 Week, Last Seen Near Chicago Hospital Where He Works

— -- A medical student has been missing for over a week in Chicago, where he's doing a two-year clinical rotation. And his brother is desperate to find him with just a few weeks to go until his graduation.

Ambrose Monye, 28, was last seen April 21 in the area of Jackson Park Hospital in Chicago, the Chicago Police Department said. He often goes to coffee shops in the Hyde Park neighborhood and the John Crerar Library, police said.

Monye, from Baltimore, is a student at the University of Guadalajara in Mexico and is in Chicago for a two-year clinical rotation at Jackson Park Hospital, according to ABC Chicago station WLS-TV. Monye was in his last rotation, which would have likely ended in May, said Margo Brooks, the hospital’s vice president of development.

Chicago police have no evidence pointing to anything criminal, but are continuing to investigate, a police spokesman told ABC News today.

Ambrose Monye's brother, Joseph Monye, who said he is also a medical student, told WLS, "We went through his apartment, we saw his reading lamp was on. His fan was on. ... He had a fridge full of groceries. ... So we had no reason to think he went anywhere or went away. Definitely he would have told me, because we're pretty close.”

Monye added: "His ticket is already booked to go for his graduation ceremony. This is very unlike him. We have no idea what could have possibly happened."

Arturo Barriga of the University of Guadalajara told ABC News via email, "We hope and we are praying for him to be found."

Monye is a black man with black hair and brown eyes, police say. He’s 5-foot 10 and weighs 180 pounds.
