UVA students say they're looking out for Harrington and keeping an eye on close friends. Harrington's disappearance has rattled some UVA students.
"I carry a knife in my bag," said UVA student Nora Ellison, "When I'm walking around at night but especially now with people going missing."
While some have taken steps to protect themselves, others say they've become more aware of their surroundings and who might be watching loved ones.

"I have a little sister here who's a first year and I told her that she shouldn't have to worry about walking around grounds at night I sort of want to retract that statement," said UVA student Steven Lenz.
State police say there was no sign of a struggle in the parking lot between the arena and athletic fields where Harrington's purse and cell phone were found Sunday morning.
Harrington was in Charlottesville with her girlfriends for a Metallica concert when she vanished before the show started. Police say Harrington was going to the restroom when she ended up outside. The arena has a no-return policy.

"There has been no contact with Morgan or from Morgan," said State Police Lt. Joe Rader at a news conference Wednesday.
