At a press conference Thursday, Fairfax County Police Chief Kevin Davis said that the search for Lu has intensified and that crews planned search for her throughout the day near where she was last seen. He announced that that the reward has been increased to $20,000. The FBI and other local law enforcement agencies are now involved in the search.

"Although I cannot and will not identify the ‘person interest’ I can share with you – it’s more than a hunch," said Major Edward O'Carroll. "We do not believe that the foul play that resulted in Mrs. Lu’s disappearance was random or committed by a person unknown to her," he continued.
