Stripping for a Grandma with a Chainsaw ERRR ERRR

In this weeks episode a stripper comes and strips for a womans bachorlette party, but to his surprise he is murdered from rage of over jealous husband. The way the CSI team set this up was a accurate measure. Even though they had the vaginal cells of a woman, they didnt test the four girls who were their. I am challenging that a person/the csi team can, should, tested to see who matched the vaginal cells on the dead stripper to see who had sex with him so they can verify there testomonies to be true or not.
