The letter was supposedly written while he was in NC.
But one of his family member could have written it post annihilation. In either case, dumb, and dumb.
Re: When CW decided to murder his family
The interview below with CW's best friend is a little confusing to me regarding the dates, and unfortunately, the text messages weren't attached.
Maybe the audio would clear things up.
But it looks to me like Cindy contacted Jamieson about the nut incident, then Jamieson contacted Chris about it, then Cindy next contacted Jamieson about the divorce, and then Chris told Jamieson himself about his plans to divorce.
So I believe that after the nut incident is when CW decided to kill them, which could been a week and a half before the murders, IMO.
I think CW viewed the nut incident and resulting estrangement as an opportunity to tell his family/friends one thing, while telling SW another.
It's impossible to fathom how his stupid mind works, but I think he actually believed that if people thought that he wanted out of the marriage, then he couldn't have possibly killed them in a rage.
I didn't seem to occur to him that there are other motives for murder and that there would be a thorough investigation, with him as the prime suspect.
I still believe he had plans to abandon her car because he searched for Audi Q7 prices before telling SW he wanted to sell the house. He also searched for Toyota dealerships.
MOO

JAMIESON said prior to that, he had a text message conversation approximately a week and a half before SHANANN and the girls went missing, and he told CHRIS to reach out to him and talk to him. JAMIESON said that CHRIS texted back but he never called and they never saw each other.
JAMIESON said that he knew CHRIS was busy, and that he had a lot going on with the family, such as SHANANN and CHRIS’ mom fighting again. JAMIESON said CHRIS’ mom, CINDY, called him about it, and that he was upset with CHRIS for letting this go on. JAMIESON said that he told CHRIS that it had to stop the fighting between SHANANN and CINDY. JAMIESON said CHRIS replied that he understood, and told JAMIESON that he and SHANANN were going to separate and get a divorce. JAMIESON told CHRIS that he was there if he needed to talk and told him to reach out to him some more but CHRIS never did.
JAMIESON said that SHANANN and CINDY were fighting over CELESTE eating ice cream that CELESTE was allergic to. JAMIESON said that CINDY kicked SHANANN out of the house. JAMIESON said shortly after this, CINDY called him crying, worried that she had lost CHRIS because SHANANN would turn CHRIS against her, as has happened in the past. JAMIESON said that is what prompted him to reach out to CHRIS with the text message.
...
JAMIESON said that CHRIS was initially taking SHANANN’s side with the most current fight, but that CINDY then contacted him and told him that CHRIS and SHANANN were going to separate. CHRIS then told JAMIESON in text messages that he had seen the true side of SHANANN and was done with her, and didn’t want to be with her anymore. JAMIESON said that he told CHRIS that he knew this would be a big event in his life and to reach out to him. CHRIS told him that he would, but never did.
