Another article from August 7th, 1980 states that she was shot three times in the chest. I keep thinking, they got rid of her clothes, personal items and covered her with lime. Like they were going really all out to destroy her identity. makes me think if she were identified, it would be obvious who the killer was.
Another very likely possibility is that she was transported there from another state to keep legal jurisdictions confused.
White powdered (Hydrated) Lime is used to cover the smell of decomposition, and to speed up the process. Someone familiar with raising animals in pens might know about obtaining and using lime.
One site described the type of weapon as a .45 Revolver. A 45 Caliber Revolver - as opposed to a .45 Automatic Pistol - is chambered for the .45 Long Colt rimmed cartridge. It was the most popular cartridge for the Model 1873 Single Action Army Colt revolver which was made from 1873 to 1942. This is the type of revolver seen in all the old Western Movies. It is the kind of revolver which must be hand cocked for each shot.
Those origional Colt "Peacemakers" are highly collectable today. In the mid 1950's Colt began making limited editions of the Peacemaker - usually commemoratives or presentation models, and prices were always high for them. While the .45 Long Colt cartridge has always been available, it had long been eclipsed by other more modern calibers and cartridges (such as the .357 Magnum, and the .44 Magnum).
A few other companies began making clones of the Peacemaker, among them: Ruger, Hawes, Dakota, etc. These other companies offered a variety of calibers for these pistols, among them the .45 Long Colt cartridge. There is a fairly recent upsurge in popularity of the .45 as well as many other cartridges and firearms of the "Old West". Cowboy shooters, dressed in authentic period clothing and armed with (mostly) replica revolvers, shotguns, and rifles of the Old West compete in a lot of matches today. As a result of that current popularity, many companies today make revolvers chambered for .45 Long Colt. But back in 1980, it would have been fairly rare for someone to be carrying that kind of weapon and using it to commit a crime.
