COOK-MORRISSEY: At 2:00 o`clock, my mother, their grandmother, called and said she couldn`t find them. They`d been on a bike ride, and you know, to come directly to Heather`s home. I only work just up the street. I came directly there...My mom had been driving around looking for them. We stood in the yard and talked for a few minutes. Heather pulled up, had not been able to find them. It was about 2:20, 2:30 PM. And so Heather said, I`m going to the police station. And that`s when she went to the Evansdale PD to involve them.
I dabble in a bit of statement analysis and this seems extremely unusual wording.
It was Heather's decision to call the Evansdale PD, not MCMs or WC's. The phrase "to involve them" sounds like it's optional, a choice Heather alone made.
Indeed, Heather went unaccompanied to the police station to report her daughter missing.
She is placing Heather's decision to alert LE outside of her and her mothers decision, which was clearly not to "involve" LE. This would be contradictory behaviour because they say they were alarmed and searching almost straight away.
The question is then, why did they not want LE involved?
