Okay....
All of you who "know" me, know I don't post often. However, this case is really bothering me. I am just thinking out loud, so please all, just take it with a grain of salt.
NCG, I am terribly sorry for your loss. I know in some small way what you are going through and my heart just aches for you and your family.
NCG said that Heather was attending AA...and that got my motor started...
If I am not mistaken, most people who are in AA have a sponsor. That being said, if Heather had a sponsor, could this person have wanted to be something more to her and was rebuffed?
Also, what if this sponsor was the one who slashed her tires, believing that she would call them for help, and they could be the "important hero of the hour?" Then when she didn't (because she had perhaps called her father, another friend, LE...) was angry that their plan did not work.
Not sure about this...but does AA have "outings"? You know, like picnics, field days, etc. that Heather would have attended with Kira and/or her dog? That being the case, then both would have been familiar with this person (hence Kira needing to be silenced and the dog going peacefully into the study).
Perhaps this AA sponsor/attendee had been at Heather's home prior and knew the layout. That might also be why Kira was calling her mother's friend...to say, "Hey <insert friend's name>...<insert perps name> is here hurting my mom" because she knew the friend knew this perp also. Little 6 year olds may not comprehend imminent danger, thus she was "telling on" this perp and trusted the friend to help, comfort, or advise her?
Like I said, I am just throwing these things out there, because when I read "AA meetings" the hair on the back of my neck stood up. Alcoholics/recovering alcoholics (not meaning Heather here) can be very manipulative, conniving, self-entitled, and con artists. More so if they are in rehab because it has been court ordered and they are not there because they want help. Additionally, court ordered attendance may indicate fingerprints/DNA being on file. Therefore the need to destroy the evidence at the scene.
I hope LE has thoroughly, thoroughly looked into any and all people who attended these meetings the entire time that Heather attended. The perp, if it was just another member, may have stopped attending months ago. They need a roster of those who attended, even if it was only once, from day one that Heather attended.
My prayers to the family of Heather and Kira and my fervent hope for justice.
