Vital Statistics

Circumstances of Disappearance:

In 1989, Morgan was charged with attempted murder--accused of beating Leone after accusing her of infidelity. She was hospitalized with two broken bones in her right leg, a fractured arm and facial bones. “David Morgan returned home unexpectedly from an out-of-state trip, and upon entering their residence he hit Diana Miller [Leone] on the right side of her face with a metal pipe,” a police affidavit reads. “David Morgan stated over and over that he was going to kill her.” Leone had to have reconstructive surgery several times from beatings. After years of experiencing domestic abuse at the hands of her husband (suspected multiple murderer) David Dale Morgan, what appears to be another altercation where her 7 year old daughter recounted seeing her father shoving Diana through “a plate glass window in the patio area of the home” and then “smashing Diana's head into the refrigerator.” Diana Leone was never seen or hear from again. She didn’t go to a hospital, she didn’t take her car, she wouldn’t have left her two young children (aged 7 and 14), she would have contacted her family and there was no activity on credit cards, phones, etc.

Additional Details:

Her husband (partner), David Dale Morgan, when asked, told people she ran off with her lover. David used that same story when his ex wife also went missing and he was alleged to have killed her lover. His own sister had, at one time, stated she was forced to help move his ex wife’s body out in the desert. David was very wealthy, lived above and owned a large storage unit which was eventually sold to magician Criss Angel. The lot still stands. David owned multiple properties and seemed to have two areas outside of Las Vegas where he may have buried at least two victims. It is suspected he may have buried Diana there as well. David has many ex lovers who suffered abuse at his hands. There may be additional missing persons. He also has several children by these women who may know more, but lived in fear. There may be aging witnesses who were living in fear, but David died on November 11, 2018 at the age of 87. The truth needs to be told so all of his victims can be found and put to rest and their families can finally have peace.
