Virginia Tech Student Missing for Four Days

Authorities and family concerned over unusual behavior prior to disappearance.

A 20-year-old Virginia Tech student, Johnny Roop, has been missing for four days after last being seen at his apartment complex in Merrimac, Virginia.
Authorities say Roop was behaving strangely before his disappearance, with his phone last pinging near a shopping mall as he was traveling to his parent's house in Abingdon.
Montgomery County Sheriff's Office believes Roop left the county on his own and traveled toward southwest Virginia or Tennessee.
Friends and family describe Roop as a family and friend-oriented person, stating it's unlike him to disappear without notifying someone.
The Montgomery County Sheriff's Office and Virginia Tech are urging anyone with information to come forward.
