Davis was introduced more than 8,000 samples of added DNA database growing in Virginia a few days. Any offender on probation the time, Davis had been arrested in a nearby regional center. Only six months later, thanks the watchful eyes of the DNA, Davis was convicted of these and other charges, was sentenced to 90 years in prison.
