First time commenting on this case,
first off, I think some people need to cut the police some slack.... I can think of 4 "local" serial killers where it took police a long time to make an arrest. Green River, I5, Clifford Robert Olson, Paul Bernardo.....
in the Green River (Seattle) and I5 cases (Washington/Oregon/North Cali I5 corridor), the perp was doing the same crime over and over again. in Green River case, same area and targeting prostitutes. in I5, doing multiple violent crimes the same day at different stops on I5.
here are comments/questions,
1) do many of us assume the perp must have specific background/knowledge? to leave so few good clues. hunting? (although that's lots of people in Idaho). ex-military? other similar guesses.
2) the dog.... surprised it didn't bark alot and attack perp..... was it bloody when found? did it know the perp? did the perp get there early and lock the dog in another room?
3) stalker... a bit surprised that dad and I think others said she had stalkers but police didn't come up with anything.... must be all kinds of stalkers at colleges..... of course, if you loosen up the definition of stalker, you'd have a third of the male population in Moscow (Idaho)
4) 9/11 call..... shocked so many people seem to think it's so important.. you get up late on Sunday, all you roommates cars are in driveway. no evidence of anyone getting up. (maybe you see dog or wonder why it's locked in another room).. roommates don't get up by a certain time, you get very confused/worried... call the police? OR, will it simply be a nuisance call?........ I just don't see how any of this is highly relevant if police figure out which "innocent roommate" made the call.. and no reason to make the "innocent roommates" lives more stressful than they already are.
5) did KG formerly live in that house? or was she still even paying rent but not living there?... never made completely clear to me.
6) sororities.... probably nothing but I watched Law and Order episode "Pledge" the other night... the perp was obsessed with sorority girls..... specific sorority, specific negative incident from way back, specific sorority sister...... horrible thing to say but I can see certain types of sorority girls rubbing people the wrong way. (of course, huge leap to what happened)
