That same day, on Oct. 13, 2022, investigators executed a search warrant at Allen's Delphi home. According to court documents, they seized, among other things, jackets, boots, knives and firearms, including a .40 caliber Sig Sauer pistol.
That latter item proved to be of crucial significance, according to court documents.
Investigators say the Indiana State Police Laboratory performed an analysis of the pistol.
"The Laboratory performed a physical examination and classification of the firearm, function test, barrel and overall length measurement, test firing, ammunition component characterization, microscopic comparison, NIBIN," the affidavit states. "The Laboratory determined the unspent round located within two feet of Victim 2's body had been cycled through Richard M. Allen's Sig Sauer Model P226."
In short, the lab found that the round had been inside Allen's gun.
That information was unveiled in redacted court documents released Tuesday afternoon that shed significant new details on the case.
