In season one, in "A Boy In a Bush", Dr. Brennan reveals to Booth "I did an anthropological profile of the suburbs as a grad student." In that same episode, Dr. Brennan reveals to Zach that she worked in Waco after Waco siege (it happened in 1993). “I was at Waco. Branch Davidian compound. I helped identify children who had been killed in the fire, seventeen of them.” However, this claim is suspect as she would have only been about 17 years old when the event occurred.
