I have wondered exactly what constitutes as gun violence. Do harpoons and crossbows count? Someone posted the answer to this years ago and it made it sound like it was specifically gunpowder and bullets involved. There have been a few cases of homemade/improvised firearms and rifles before.
There is also not shortages of cases where the stab wounds were so bad, it was assumed the victim was shot at first.
One other theory is that the perp used one of his tools to (at least attempt to) remove the bullets from Missy, causing confusion about the existence of puncture wounds.
I believe it was LordonArts who used a case search feature circa 2018 or so and it narrowed down to Missy's specific age and exact date of death, not naming her by name but stating the victim was female and died from a gunshot wound. Many posters have claimed this as gospel, but I have never personally seen a link for this information and anyone that brings it up evades posting any evidence of their findings. I don't discount it, but I would like to check it out for myself.
I have provided this for you before. The page is a screen grab straight from the FBI's UCR files. (They were in person and investigating it from the day of the murder.)
1 They have a massive database on crimes committed in the US, which by law is made available to LE and to researchers.
2 Their search engine seemed almost impossible to navigate from the outset - having been told it was there somewhere, it took me MANY MANY hours of various inputs to finally find a path to the info. You have to use what we know, in odd screens where they ask for this but not for that, and eventually work your way to a results screen.
3 I did find the info multiple times (and shared it in this forum) and others found ways to do the same. The crimes are not listed by name, so you have to enter some parameters to make it unique. It's helpful that Midlothian and Ellis Co have few unsolved murders.
4 Each time took trial-and-error and MANY hours of persistence. You have to put in just the right search inputs, in just the right order, and navigate through multiple searches to get what is buried there. I would try this, then that, over and over. I landed back at start with much frequency.
5 I learned the hard way that there's not a defined path to get there again - it can be repetitious and feel like luck, and what works one time doesn't seem to work the next. You have to find the right search page, then use just the right parameters (what we know of the crime, the victim, etc), and hope you do it in the right order.
6 Also it's behind a wall that does not let you copy a URL and return to the results at your leisure. Each time, you have to trial-and-error anew for many unpredictable hours.
7 Unfortunately, in the years since, they kept changing their search screens and input options, making the path different and more difficult imo. The last time was my personal "last time" and I just made a screen shot and decided "never again."
8 Depending on the path you take, the search results come up in varying ways. Below is the result I happened to get the last time, when I decided I wasn't doing it again.
9 It could be easy now. I dunno. I don't have any reason to undergo the beating again and find out.
FWIW, there is a website (Murder Accountability Project) that D/L'ed the database and layered their own search engine on it. The info was there as well in their own search results, although formatted a bit differently. There may be other research orgs that have it online. That could be a secondary path. I can't promise who has what, anymore. But they had the same info, of course -- she was killed with a "Handgun - pistol, revolver, etc". If one is too frustrating, maybe another works for you. But it was always a long project for me to look up each time, and some times I would bail because I couldn't figure out how to get there this time with their latest overlays.
If you wish, you can theoretically look it up yourself.
