I realize there is insufficient data at this time to call the perp a serial killer, hence my "JMO".
Official FBI definition of serial killer:
"In combining the various ideas put forth at the Symposium, the following definition was crafted:
Serial Murder: The unlawful killing of two or more victims by the same offender(s), in separate events."
https://www.fbi.gov/stats-services/publications/serial-murder
All this guy needs to have done is to have killed once before, and
JMO he almost certainly has. If he hasn't yet, then
IMO he probably will again and
IMO LE agrees and feels the need to tell the entire USA to BOLO via those 6000 billboards, etc.
I realize most of these crimes are sexually motivated, however
IMO that was not the primary motivation here though it may indeed have occurred.
I maintain my "since the beginning" suspicion and assertion that
IMOthe COD will be strangulation.
I, too, believe (
IMO) he did this opportunistically and not as a result of pre-meditation in relation to these two specific girls.
When looking at statistics for stranger abductions and murders, we find that it is INCREDIBLY rare to abduct two at once, and it's almost as good as a calling card, like writing "helter skelter" on the walls... so,
IMO this is either NOT his first time, or NOT his last time.... IMO... because with STRANGER abductions/murders, the "normal" motivation that one might consider in a case between relatives/friends/co-workers/etc is lacking - it's not a matter of long-building anger, resentment, rage, of interpersonal conflicts, etc... it's something INSIDE the perp... and that doesn't go away after he does it once or twice... all JMO.
I don't mind being wrong though as long as he's caught and brought to justice.
