Hi - what was Burke's response to improper touching.
He curled up into a foetal position and began making noises if I remember rightly.
The chapters that focus most closely on Burke are entitled Enigma and SBP and Beyond. In Enigma, Burke is reported by psychologist Susanne Bernhard to have exhibited signs of anxiety when asked unspecified "key questions" about sexual contact: "he picked up a board game [they] were playing and was rubbing it on his head...the display of this body language contrasted to the behavior exhibited as a baseline throughout other parts of the interview" (page 349, Kolar). This behavior was repeated following a question about JR's claim to have discovered JBR's body in the basement.
When questioned by an investigator about specific details of JBR's disappearance, Burke "retreated into his chair in a fetal-like position, and he seemed agitated and nervous" (page 358, Kolar).
There could be other citations - Kolar's book needs an index. It is packed with detailed information that is very hard to locate after the fact.
