*67 is 100% in the control of the person dialing it and making a call using it. *67/number blocking cannot be controlled by anyone else other than the person who dials it, thus the choice to use *67 is about control -- control over whether a name or phone number will be shown to the receiver of the call.
A several day or several week pattern of SA's calls is not necessary to ascertain what he did on the very day in question. The fact is he made about 16 calls that day and the only person he blocked his number to was TH the two times we know for a fact she was still alive. Clearly the number blocking feature was not set by default -- he had to dial *67 each time to block his number and he chose to do so.
Since the defense presented no evidence of their own or any explanation of why SA did this, nor did they present any evidence showing SA had a specific pattern of calling blocking, there's no reason to try and make up an excuse for SA's actions.
No evidence was presented to show TH made any other stop after the salvage yard. Assuming she must have done so in order to not make Avery the last stop and thus find someone else to blame (ABA/anyone but Avery) doesn't work. TH's phone's last known activity was around 2:45pm Oct 31. There is no evidence she was ever seen or heard from again by anyone in her life who knew her after her stop at the Avery Salvage Yard. Her phone was found destroyed, at least partially melted, in a burn barrel at the salvage yard. By the time SA made his 3rd and final call to TH, he chose not to dial *67. And, coincidentally, TH's phone could never connect to a tower again. A trained LE canine officer is who found the evidence--the scent which led human officers to that burn barrel and detected the scent of human remains.
The evidence is what it is, the calls are what they were, her charred body remains were found in SA's burn pit, buried under a layer of ash, intertwined with steel rims from tires used as accelerant. There is no evidence TH's remains were planted there.
Some theories will go as far as claiming TH was not killed, those weren't really her remains, there was no homicide, but if she was killed, then it was someone in LE who killed her and then burned her body and planted her remains. Not even SA's two highly regarded defense attorneys, who gave SA an aggressive defense, claimed that.
Then how do you account for the fact that Theresa Halbach's phone records show that she was still alive when she left Avery's salvage yard?

According to Zellner, the last call Halbach's phone received pinged a cell tower located 12 miles from the Avery Salvage Yard. "It's absolutely shocking to see cellphone records that were part of the discovery that were turned over to the defense ... document her route leaving the property," Zellner told Newsweek. "It's really hard to figure out how in the world did the defense not seize on this. It would have created reasonable doubt."
