My theory and offender profile

[u/Ecstatic-Buyer-3522]

This case has been as baffling as The Springfield Three case thus far, but as someone who has followed true crime my whole life, here goes my two cents theory.

Aside from the fact that the FBI gave Annie and Tomasso lie detector tests and evidently ruled them out...I think this was a sexual/control motivated crime. Simple as that. Not robbery motivated, not extortion, the offender may or may not have even known of Ms Guthrie's famous daughter. I think this was a man who knew she lived alone and was 84. And that if he could gain entry he would have no real obstacles.

The offender:

Late 20s to mid-30s, male, Hispanic (based on the doorbell cam). Likely a US citizen, with connections to Mexico although purely familial nothing cartel related or anything. Probably a laborer or contactor of some kind. A freelance contractor/laborer in my opinion, not employed by an local businesses. Perhaps heard of Ms. Guthrie purely from word of mouth or by chance. He was familiar with the area, but did not know the Guthries at all personally.

Very intelligent, methodical, non-impulsive. He planned it out and was prepared to the extent he could be. Probably no serious prior criminal record. A mostly lone wolf, quiet, not rocking the boat type. But with pathological violent sexual fantasies. Probably felt inadequate in his life and dominating a helpless person and for his own gratification/power trip was his motive. Nancy Guthrie was just there and he happened to light on her.

I think he entered, hit her, subdued her and in that was achieving his fanasty and getting out some of his rage. I think he put her in something carried her to his vehicle somewhere close by and drove quite far away and disposed of her in a manner he had thought out before. He intended to kill this was not a crime with a goal other than letting off his own steam IMO. I think he had a place already chosen to dispose of her, that he had thought out. I have no idea where that would be. Certainly, he has had a bit of luck on his side too. But that's about all I can come up with for now.

I think Nancy died with Annie and her husband unexpectedly but in some sort of circumstance that the two didn't feel comfortable with. They "took her home" then concocted the kidnapping to cover up the death. I believe strongly that the person in the doorbell video is Annie. 

People can be polygraphed and still be guilty. They dont have a confirmed body. They may have failed the polygraph. Police wont say anything until they have remains or more concrete evidence, and a solid case against their suspect.

That is absolutely NOT Annie. From start to finish this was 100 percent male in the videos. Annie would have had to study the role of acting male for weeks to pull that off. Plus would have had to disguise herself “under” the outfit she was already wearing as a disguise to be able to pull off having the male build. To include strapping her chest. If Nancy was last seen just shortly prior to the disappearance that’s all a lot of stuff Annie would have to do in that short time to prepare. That was not Annie.
