Toms River University of Maryland student Kaitlyn George missing in Maryland

Police in Maryland are searching for a 21-year-old Toms River college student who has been missing for the last four days.
Kaitlyn George was last seen Thursday on the campus of the University of Maryland, where she is studying aerospace engineering. University police say that she was supposed to meet her boyfriend at the university rec center for a camping trip, but never showed up.
She was supposed to meet her boyfriend around 5 p.m. A surveillance photo shows her leaving her dorm at 4:45 p.m.
She is then seen getting into a taxi on campus and taking a ride 30 minutes away to Baltimore. From there, police say she is seen getting into another car alone. 
A witness tells police that George was seen Friday morning on a Baltimore shuttle. She has not been seen since.
George is 5 feet 3 inches tall and 120 pounds. Police says that they do not suspect foul play in this case but that they are working hard to find her.
George's family has traveled to Maryland to help look for her.
