Leos are hesitant to arrest anyone without good evidence these days. They knew he did it, but had nothing to prove it.How did / why did the North Port Police or the FBI NOT see this guy "vanishing"?
With all the digital surveillance these days, most are easily caught . This guy will be found well inside a week, alive or dead.
Plus, they aren't paid any more for arresting a guy early rather than waiting for proper evidence.
