A campus-wide e-mail sent Wednesday by the dean of students says police in Swarthmore Borough, about 15 miles from Philadelphia, have opened a missing persons investigation.
Baldwin is described as a white male with shoulder-length brown hair, mustache and a fair complexion. Baldwin wears glasses and might also be wearing a dark green parka and black leather boots.
The school was first notified of his disappearance by a friend on Tuesday.
Anyone with information is asked to call 911 or the school's public safety department at 610-328-8333.
