I am surprised at the level of interest in this situation. We knew that this was an unusual homicide given the firearm used but, after reading all of these posts, I get the opinion it is even more rare than I originally thought - which is a good thing!
My original post in this thread had a two-fold intention. First - just for the information to those here about what happened, second - to put out to those who would probably know best, what prosecutors and ATF people were telling us with regards to the charges applicable in this case. We, the local P.D., knew there were some differences given the fact than an antique weapon was used but, I and those involved in the actual investigation didn't have the time to research whether or not what we were being told was correct. After reading the replies to my post by Monday morning it was clear that there was something amiss with our legal information here. I then looked into the matter myself and made some phone calls. What I learned was yes, it is correct that our shooter in this situation, though he is a felon, could in this state possess a BP firearm and the necessary stuff to load and fire it without violating any state or Federal laws. So that much they told us was correct, the legal reasons why this was possible are not what we were originally told however. What appears below is long but, since there is an interest I have included it here. This is part of the text of a memo I sent to the detectives involved regarding the Federal regulations and state statutes which apply in this case with regards to the felon in possession decision. Any additional feedback on this would be greatly appreciated - thank you all for the help here.
