NEW HAVEN, Conn. — Investigators pored over blueprints and surveillance video footage Saturday at a Yale University laboratory building where a graduate student went missing just days before her wedding.
Security records show Annie Le swiped her identification card to enter the building about 10 a.m. Tuesday, but there is no record of her leaving, despite some 75 surveillance cameras that cover the complex.
Nearly a dozen unmarked police cars lined the sidewalks around the laboratory building in the Yale Medical School complex.
University Vice President and Secretary Linda Lorimer called it "entirely perplexing that there doesn't seem to be a record of her" leaving the building, according to the Yale Daily News. Lorimer didn't immediately return a phone call to The Associated Press on Saturday.
Investigators, having already gone through the videos once, were reviewing the surveillance tapes frame-by-frame to see whether they overlooked Le, who could have changed into a laboratory coat or other clothes before leaving the building.
On Saturday, they brought what appeared to be blueprints to the building. FBI agents also were spotted questioning an unidentified man outside the lab. When they finished talking, the man got in the front seat of the unmarked car, and an FBI agent got in the back seat. The car then drove away.
Agent Bill Reiner said the FBI wouldn't answer any questions about the investigation while it's ongoing.
Yale is offering a $10,000 reward for information leading to Le's whereabouts. She is described as being of Asian descent, 4 feet 11 inches tall and 90 pounds. Her purse, cell phone, credit cards and money were found in her office.
Officials say there's no evidence of foul play.
Le, originally from Placerville, Calif., was set to get married Sunday at the North Ritz Club in Syosset, N.Y. Workers at the club say the wedding was canceled Friday.
Police say fiancé Jonathan Widawsky, a Columbia University graduate student, is not a suspect and is assisting with the investigation.
Meanwhile, at Le's neighborhood across town, hopes for her safe return waned.
"I feel bad what happened to her," said Anna Beth Funk, who lives across the street. "It broke my heart hearing she was about to get married because I love being married and it must be so hard for her fiancé."
