I'm sorry for your loss and I hope the law catches them.
Does remind me of a funny story through,
***|Sea Story Warning|***
Actually not a sea story,
My mother worked as a dispatcher for the Brevard County Sheriff's Office on the grave shift.
Very early one morning, when there was little comm traffic, the deputies started hearing someone not using SOP on their freq.
Listening in the deputies determined that the two perps were attempting to break into a warehouse. They were using two radios stolen from from another county that used the same freq as BCSO. Needless to say they were caught and had the experience of going to trial in two Florida counties.
Hope this brightens your day a little.
