Missy was not shot. She was bludgeoned to death with a hammer or similar tool.
I think this is public information now through records that were pulled by the press/ unsealed.
You have been misinformed. Missy was killed by being shot. The Weapon that caused Missy's death was "Handgun - pistol, revolver, etc" according to the FBI crime files (screenshot below).
FULL EXPLANATION
Those files are available to the public (in a massive file, and the search engine is very User UN-friendly to try to navigate).
(I did the journey several times, and shared the info with others here who also found it, and we posted what was found multiple times with screenshots. That was years ago. There was no URL to share because it was buried behind search engine layered on search engine to find it, taking trial-and-error and luck, and several hours of frustration when successful. They have changed the system more than once since then. Even with notes, the path varies, and it's a trial-and-error journey that may end with no success. I don't bother anymore, but I have a picture below.)
In the initial PC on DOD, LE explicitly declined to say how she was killed ("we're not releasing any information on her injuries right now") and deferred to the ME's upcoming examination. A few SW's became available in a week or so to the media, and released to the public, and one (originally dated on the day after death) included this snippet: "
Terri Bevers’ had multiple puncture wounds found on her head and chest are consistent with the tools the suspect was carrying throughout the building." That was all that was ever "said" about her wounds - after that, nowhere (in any PC or SW) did they say anything at all about wounds.
That oddly worded sentence was the basis for our belief she was killed in some other manner. After that, until we had the FBI info, we assumed any mention of a gun was weirdly off-base, or just a rabbit trail where LE was chasing just-in-case things. We thought the SW had told us she was probably bludgeoned with a hammer or crowbar or flashlight or the like.
Of course, looking closer, that wording does NOT say she was bludgeoned. It says "puncture wounds." That's not a bludgeoning.
After we learned more via the FBI file, it seems like LE might have been trying to obscure with technically accurate - but "likely to be misunderstood" - wording. The SW does not define "puncture wounds" or "tools" or say that they necessarily killed her. TECHNICALLY - bullets puncture the body so they can make puncture wounds, and a gun is a tool for shooting someone or something, and loser perp certainly must have been carrying it in order to use it. It is possible that she was ALSO wounded by hammer/crowbar/whatever that did not kill her, but personally I doubt it. In any event, LE was certainly trying to obscure the public from generally knowing she was killed by a gun.
They accomplished their goal, it seems. It's been 10 years, and still that fact is not widely known.
There's more that tells us LE was actually chasing a GUN death. From records obtained by FOIA release (which we didn't have for quite some time, several months or more iirc, well after initial impressions had been been formed), we learned
in the hours immediately after her death, LE was conducting searches for suspicious retail
handgun sales and
ammo sales in the surrounding area, for the days immediately prior to the murder. They also got a SW for her truck, in part to find and/or seize any possible gun (with the idea she may have been killed by her own gun). There was a big FOIA tussle over the gun's S/N that was in the picture (which in hindsight must have been MB's, known to them).
Anyhow, in light of all that, it is my belief that LE carefully worded their SW info that spoke of wounds to obscure her actual cause of death from the public. And then decided in later SWs that wasn't necessary anyhow, and said nothing. Why? I don't know.
TL;DR/ MB was killed by a gun.
