Looking at things as one large picture (in hindsight, of course), BK moving to Pullman and getting a new phone number, as a 28 year old student, might be telling. It has the feel of a "fresh start," which there isn't anything inherently wrong with, but seeing how things sort of spiraled for him from there, it makes me wonder why he needed the "fresh start" to begin with, especially with a new number. The confrontation with students and staff, the troubles with his TA job, etc., don't feel as much like triggers as they do yet another signal of how he was functioning. I can't call them triggers to the murders, even though the timing might appear so, because I think the PCA is suggesting that BK started possibly stalking the King RD residence as far back as August 2022, not too long after he arrived. I'm sure there was a compounding effect with it all, but I'm curious. Why did he need a new phone number?
I'm not "diagnosing" BK because (a) I'm not qualified to do so; and (b) nobody should assign a diagnosis from afar; but I think it's clear he was "decompensating" in a major way. Being so far away from home for the first time PLUS the general pressures of anyone's first year in a doctoral program PLUS his problems TAing with both the professor and the students PLUS his seeming inability to create a new group of friends are all stressors which can contribute to decompensation.
Oxford definition of "decompensation" in psychiatry (the part I deleted deals with schizophrenia and I don't think anybody has called BK that):
- PSYCHIATRY
the failure to generate effective psychological coping mechanisms in response to stress, resulting in personality disturbance or disintegration....
