On the evening of May 1, 2008, multimillionaire real estate developer Hal Wenal came home to find his wife, 60-year-old former model Eva “Kay” Wenal, lying face down in a pool of blood on their kitchen floor.

Kay had been punched several times, and her throat had been slit almost to the point of decapitation, investigators later discovered. There were no signs of forced entry, and nothing had been stolen from their upscale home.

The assailant, however, did leave behind a bloody towel in the closet of the couple’s master bedroom. It had been placed on top of a locked cabinet that contained Kay’s jewelry and — surprisingly to Hal — several pieces of leather lingerie. A male DNA sample was found at the scene, but authorities were unable to identify it.

Although local media received a note made of magazine cut-outs from the supposed killer a few months after the slaying, investigators in Gwinnett County, Georgia, were unable to obtain any DNA evidence from it, and the case has since gone cold.

Could Kay’s murderer have had a financial motive or been a scorned lover looking for revenge? In the hopes of generating new leads and investigative avenues, the case is now being reexamined on “The DNA of Murder with Paul Holes,” airing Saturdays at 7/6c on Oxygen.
