Select It Sunday: Diana Leone

A friend of Diana L. Leone‘s sister asked me to run her case for Select It Sunday. Diana was 35 years old when she disappeared from Las Vegas in February 2000.  Her longtime boyfriend, David Morgan, said she’d run off with another man, leaving all her stuff behind. She wasn’t reported missing until October.

Morgan had a history of brutal domestic violence against Diana — he’d once been charged with attempted murder in connection with his abuse of her — and police believe he’s a serial killer. His second wife, Marie Morgan, and her lover, Gabriel Vincent, disappeared under suspicious circumstances in 1979 and were never found. A business associate of Morgan’s, David Cowan, disappeared in 1982 and was also never found. (Cowan and Morgan aren’t on Charley cause I have no photos or physical information for them.)

Morgan was actually charged with Vincent’s murder in 2007, but five years later, before he was tried, the charges were dropped for lack of evidence because one of the key witnesses had died. Police are pretty sure Morgan killed Diana as well, but he has never been charged. I’m not sure he’s even still alive.

      What makes you so sure that’s him? I mean, granted, it very well could be, but David Morgan has got to be quite a common name.
