in MOO there are a few similarities. Abducted at trail head. Two hikers forced into trunk at gun point. He started his killing spree, as far as I can tell from the news stories, in Mississippi. He, according to news stories, killed his girlfriend and another person there, shot a jogger. No explanation of why he came to New Mexico. But we do know, according to news stories, he continued to flee authorities and shot more people, stole cars, etc and ended up being apprehended in Kansas after a car chase and horrible, firey rollover.
According to the news report in The Albuquerque Journal (abqjournal.com) either 3/1/17 or 3/2/17, it mentioned this spree might not have been the first time he had murdered. Also, IMOO,, his girlfriend that he murdered may bear a resemblance to Abby.
Being that it reported he was in several states during this crime spree, it is possible, IMOO, that he may traveled to other states.
In one off the articles about this crime, there are 4 work badge pictures to show what a cameleon he might be, and his mug shots are interesting. There is one full length mug shot, and it appears, IMOO, that his feet spread outward. I haven't heard any updates as to whether he is in Kansas or Mississippi--I think I read the states were trying to decide who would try him first.
