PITTSBURGH — A University of Pittsburgh student last seen in April was found apparently living among homeless people in Montana, authorities said.

When a ranger at Glacier National Park came across several people Thursday and asked for their identification, one of them was Pranesh Patel, said Pittsburgh police Lt. Daniel Herrmann.

Patel was spotted again at the park Friday, according to his brother, Tarak Patel. Family members planned to fly to Montana to try to locate him, according to his brother.

Pranesh Patel, 23, of Sicklerville, N.J., was not detained by authorities because he hadn't committed any crime.

Patel was last seen April 24 when he left the home he shared with two others to take an electrical engineering final exam, for which he never showed up, his roommate John Vroom said.

Patel was afraid to tell his family he might not graduate, Vroom said.
