I don't think that CDR, in Ames, was a copycat of CBR in Brooklyn at all. In MT's case, very few details have been released that could be copied, no LE details or confirmation of a SA has been given. No details of the weapon used or how many times or where MT was stabbed, other than a vague "sharp force injury" (which could include the claw side of a roofing hammer) and a passing, single mention by the ME of a "sharp object like a knife" on interview. In CDR's case, all of this and more (except SA allegations) have been released within 2 days of the murder.
No, I think that CDR simply had an itch, and scratched it, as he told his homeless camp mate: "I feel a need to rape and kill a woman".
CDR even had a "Let's commit murder" meme on his Facebook cover page. One wonders how many more women he has killed in his native Iowa. Recall all the up-thread discussion of CBR possibly being an experienced, violent, serial rapist? Go look at CDR to see what one should look like. I would LOVE to see the browsing history on his smartphone (I would, of course, wear gloves). Like CBR looking at LE attention focused on the "hog farmer", perhaps CDR felt the same relief (or more) when LE grabbed CBR, and he lead them to his one dead body in a corn field.
Another similarity between CDR and CBR, is that they both lived in underground communities that would have many reasons to NOT call LE about a homicidal nut job. If you call the police onto a Hobo Camp, you won't have many friends left.
