I don't know if there is a connection, but it's certainly possible.
I do believe many uncaught serial killers are nomadic killers going to different states once killing multiple victims in one state.
Doesn't the FBI keep computerized records on unsolved cases involving multiple victims where the killer's MO is the same?
Iirc different LE jurisdictions can put in their unsolved cases to see if other states have multiple victims with the same like patterns used by the killer or killers.
Although quite a few SRs are above average intelligence, and can change their MOs in order to evade them from being connected to their other victims.
I believe Clements who has been charged with the murders of 6 year old Isabella Celis, and 13 year old Maribelle Gonzalez of Tucson, AZ is also a possible serial killer.
When he moved to AZ he was an absconded sex offender out of Florida.
He never registered as a sex offender even though he has been one since 15 when he assaulted a minor child.
Shades of the serial murdering pedophile monster Joe Duncan who also moved from state to state to do his kidnappings, rapes, tortures, and murders.
CC has lived in several states again never registering. In AZ he told his now ex girlfriend he had 4 bodies buried in the desert. The only ones who have been found is little Isa, and Maribelle.
I wish someone here would investigate Clements too, and his whereabouts before he was finally caught. Imo, I think he too is a nomadic pedophile murderer, and possibly a serial killer of young children.
Sorry to go off topic, but this thread just reminded me of his case.
