MEMPHIS, Tenn. – A 67-year-old man who previously served prison time in the murder of a 6-year-old child, pleaded guilty to a 2001 rape. This occurred after investigators linked him to the scene of that crime through a pair of dentures he left behind.

It’s not unusual for crooks to leave behind condemning evidence to do them in. That is how many crimes are solved. Among the incriminating evidence would be fingerprints, DNA, the occasional drivers license or wallet, and even cell phones. But dentures? That is unique.

The dentures were part of a sexual assault kit backlog that wasn’t tested until recently. Although authorities may have been able to identify Thomas Maupin (pictured) sooner as his name was printed on the inside of the false teeth.

If ever a calling card were left, that would be it.

You might say Maupin’s dentures took a bite out of him. He was sentenced to eight years in prison for raping the 31-year-old woman in Memphis in August 2001, FOX 13 Memphis reported.

At the time, police said the victim was approached by a motorist who got out of his car and started walking toward her. A pair of dentures recovered at the scene were collected and tagged by investigators as part of the sexual assault kit.

The kit was later booked as evidence. Sadly, it became part of an enormous backlog. Consequently, it was not tested until July 2016, WREG reported.

Officials from the Tennessee Bureau of Investigation were able to eventually match the dentures to a partial DNA profile of Maupin. Yet in addition to the DNA match, someone (presumably from the crime lab) also discovered his name printed inside.

The dentures were originally made while Maupin served time in Washington state for the 1988 murder of a 6-year-old girl. He was twice convicted and sentenced to 40 years in prison, but the convictions were overturned on appeal.

He then relocated to Memphis after serving 12 years in jail.
