PERTH AMBOY - Police are searching for a college student from Perth Amboy who went missing a week ago following a car crash.

Family and friends of William Gu say they have not seen the 22-year-old since March 7. They say the last time they saw him he was on his way to school. However, police found his car damaged in front of the Somerset Diner on Easton Avenue.

Gu's family is worried because in 2011, he suffered severe head trauma during another crash. They say he has suffered from bouts of depression, paranoia and minor hallucinations ever since.

A missing person's flyer is posted in the lobby of the Somerset Diner. Police have also searched the nearby woods and waters, but have found no clues.
