Annie Marie Le, 24, a pharmacology grad student at Yale University, has disappeared days before her wedding. Le's roommate reported her missing after she failed to return home on Tuesday. Tuesday morning, Le used her university swipe card to enter the lab where she worked. Police are searching the lab's surveillance video to see if Le left when the building was evacuated later that day. Le left behind a purse with her cell phone, credit cards, and money. According to her fiance's roommate, Le and Columbia University grad student Jonathan Widawsky were an extremely happy couple, and Le was not the type to get wedding jitters.
