Early this morning, about 1:30 AM, BA called and asked for Police 1's assistance in locating a girl who had been abducted and left in the woods where she was unable to move but was able to call police and tell them where she was. The first thing P1 said was how are we going to talk to them, there was no way the systems were compatible. The dispatcher called BAPD and asked about it. They ended up going to RMA-2B (38224) and communicating for the search. Good thing it only lasted about 5 min. because they were about to piss P1 off as he was leading them to the body and they wouldn't follow his directions. " If your all just going to walk in every direction..." When all was said and done, they didn't even say thanks or acknowledge his last few transmissions!
