GENESEE COUNTY, MI -- The online sale of a pair of panties allegedly crocheted by an Imlay City woman serving life in prison for three murders has brought exposure to an industry that has largely avoided the state of Michigan.

Florida-based Serial Killers Ink is selling what it claims is a pair of panties that were crocheted by Samantha Bachynski. The sale, which is listed with a slightly varied spelling of Bachynski's last name, claims the underwear is signed by the murderer.

Bachynski, 28, is serving a life sentence without parole after she and her fiance, Patrick A. Selepak, went on a 2006 rampage of theft and robbery that left three dead.

"Murderabilia" dealers, or people who specialize in the sale of artifacts associated with notorious crimes, have largely avoided Michigan due to its lack of high-profile killers, according to Andy Kahan.

Kahan, who works at the Mayor's Crime Victims Office in Houston, said he monitors murderabilia dealers as he advocates for laws limiting the ability of criminals to profit from their crimes.

Here are the oddest items Kahan has ever seen sold or offered for sale by murderabilia dealers:
