The best predictor of 'future' behavior is 'past' behavior. When I look at the patterns created by criminal actions perpetrated by WH, it is very hard for me to ignore him as the number one suspect.
At 19 he takes a 15 yr old girl on the run across state lines. Breaks a few laws and does some jail time I believe. They stay together awhile and have a baby together. But his initial impulses were WRONG imo. But he could not resist the temptation of a beautiful younger girl.
Later, a similar but WORSE incident with his 21 yr old ex wife, who initially left him because of domestic violence. He nabbed her and ran, stayed on the run, held her for weeks and robbed a bank. Charges were dropped but the woman's father said it was because she was afraid to testify against him.
But read the GRAND JURY transcripts which led to his indictment. [ linked way upthread] She said he strangled her, punched her, raped her and held her hostage.
Sprinkled in between these violent domestic violence charges are arrests for burglary and B and E. He also has mental health issues, is unstable and admits to abusing drugs.
Now you have a recent break up of this marriage, and potential loss of 'his girls' over his drug usage. he is living in a seedy hotel and probably very resentful. This seems like the exact same pattern that set off his past violent outbursts.
On top of all that, he placed himself as the last known person to meet with AJ, 'until she departed his presence.'
I don't want to have tunnel vision, but it is really hard to look away from this guy since he was 'leaking ' like crazy during his word salad rants and dropping red flags all over the field.
