Well yes and no IMO. Very observant btw!

Great insight.
but JMHO here and I guess expanding on what you noticed so well.
These men are not great thinkers. They don't have a great variety of interests or thought. So they do what they know...which is limited in scope to be generous.
So yeah, the landscaper most likely put her in the landscape somehow some where and used the mountain lion...I mean bobcat. And something horrible happened in the house...we know that cuz why else would it smell like bleach?
and also IMHO....they also all have being an idiot in common.
Watts was not a great oil field worker...he could have blown himself and co-workers up. Idiot.
Frazee...mama's boy to the end...even burns his victim on mama's land with a witness. Idiot.
Peterson...not a good fisherman. LE got him tripped up on the bait/lure he was supposedly fishing with. Idiot.
BM...a mountain lion....even though there was no blood, no animal fur and there was an important personal item found no where near the bobcat...I mean mountain lion attack. Plus he bought tons of bleach/chlorine and has no pool.
Idiot.
