Investigators, having already gone through the videos once,continued to review the surveillance tapes frame-by-frame Saturdayto see if they overlooked Le, who could have changed into alaboratory coat or other clothes before leaving the building. Mertzsaid the review included video enhancement being conducted by statepolice.
"I do not know that it's definitive that she has left thebuilding at this point," Mertz said.
On Saturday, investigators took what appeared to be blueprintsto the building. FBI agents were also spotted questioning a manoutside the lab. When they finished talking, the man got in thefront seat of the unmarked car and an FBI agent got in the backseat. The car then drove away.
