Investigators sifted through garbage at an incinerator Sunday, looking for clues into the disappearance of a Yale University graduate student who was supposed to be celebrating her wedding day.
FBI agent Bill Reiner said Sunday that investigators are "following the trash" that left the university laboratory in New Haven. He declined to comment further on the search at the Connecticut Resources Recovery Authority's trash-to-energy plant in Hartford.
Annie Le, 24, was last seen Tuesday morning at the lab. More than 100 state, local and federal law enforcement agencies are looking for her but have not yet determined if Le's disappearance is a missing person's case or an act of foul play.
Authorities say Le, a pharmacology doctoral student originally from Placerville, Calif., swiped her identification card to enter the lab. But there is no record of her leaving despite some 75 surveillance cameras around the complex. Her ID, money, credit cards and purse were found in her office.
Investigators on Saturday said they recovered evidence from the building that houses Le's laboratory, but would not confirm reports by media outlets that the items included bloody clothing.
In a story published Saturday, the Yale Daily News quoted an unnamed New Haven Police Department official as saying the bloody clothes were found in a ceiling at the building. The official spoke to the newspaper on the condition of anonymity so the official would be free to discuss an ongoing investigation.
On Sunday morning, a state police Major Crimes Squad van drove down a ramp into the basement area of the building where the lab is located. Officials had no immediate comment.
Yale is offering a $10,000 reward for information leading to Le's whereabouts.
