Suspect List

Prequel to this [link] .
So Principal Bittermann got shot and now a gung-ho detective (who is probably breaking a certain number of laws) wants to find out who shot her. He has rounded up a list of suspects (an exhaustive task) who are red herrings.
Gayle Stromsberg and Molly Forbes: Molly was the Principal's ex-girlfriend and Bittermann has a special hatred for Gayle; taking this out on the children. Don't mess with two Mama Bears.
Dementia "Demi" Cross: Her new young girlfriend who sensed that Deana still loved Molly. Was Demi acting out on a broken heart?
Thanksgiving "Hank" Forbes-Stromsberg: Skinny, good-natured, Pollyanna-ish Hank always bore the brunt of Bittermann's anger. He is assigned the tough gym classes. This Emma Watson fan can handle a small pistol though.....
Wayne and Jean Riley: Their daughter Roberta "Bobbie" was another target of Bittermann's temper.
Jamal Ween and Josef Picklelohchi: Jamal attended the same arts and crafts camp as Deana when they were kids. Deana started eating frosting that was to be used for a baking project, Jamal panicked there wouldn't be much left and then scooped the frosting out of her mouth. Did I mention she made it hell for their kids too?
Barbara "Babs" Ween-Picklelohchi: Daughter of Jamal and Josef and Vice-President of the Johannes Valley High School Hair Club, who's former member was Molly Forbes. Bittermann cut out hair-related texts from the club and class related curriculum. Also Babs has a crush on Hank.....Hmmmmmm......
Tyra La Dou'che: The Bad Attitude of Johannes Valley High. Bittermann took her IPod, hairspray, chewing gum, air pump (for hair and other purposes), nail file, nail polish, and spare thongs (to rent out to boys who want "proof"). Oh yes the Principal took her cosmetics (to be fair, it could be used as weapons in her hands) and shut down a successful business.
