St. Michael necklace as explosive residue
Rumor Contested Alternate mechanism
Owens Ep 351: federal interest in Kirk's St. Michael pendant is explained if the pendant held explosive residue from a rigged mic. No residue lab is in this file.
A family keepsake after a homicide is the commonest reason a necklace is collected. Residue is a lab result. Do not treat chain-of-custody curiosity as PETN. This file will host a residue report if one is produced. It will not invent one.
