Forensic Ident Officer Bruce Templeton defines the house/murder scene as a squat. This is correct. However, he claims that it is called such because "of course that's what squat means, we squat and do our thing." This is in reference to an earlier statement that "there was human excrement all over,".
The word squat is defined as a verb, to occupy or reside in without permission. This dates back to approximately 1800. The use of squat to define the action of defecation is from 1934.
