A good cop friend of mine and I were kicking it recently, and we got to talking about body disposal. Lime, as a solvent was referenced, and he said that John Wayne Gacy was discovered as a murderer because the lime that he used was not ‘the right type’ to dispose of bodies, while there were, in fact, other types that would have let him get away scot-free. (The stench of the bodies under his house was what helped investigators track down some of his victims’ bodies.)
My friend isn’t a forensic investigator, by any means, and wouldn’t swear to any of this, but, he believes it.
I had to turn to the SDMB. Is my friend correct, and did Gacy use an inferior type of lime for his grisly purposes?
