Latest Missing Person Photos for Missing Diana L. Leone








Missing Since 02/01/2000

Missing From Las Vegas, Nevada

Classification Endangered Missing

Sex Female

Race White

Date of Birth Used 08/03/1964 (56)

Age 35 years old

Height and Weight 5'5, 120 pounds

Clothing/Jewelry Description A white t-shirt, blue jeans and a watch on her right wrist.

Distinguishing Characteristics Caucasian female. Blonde hair, hazel eyes. Leone has previously fractured her left arm, right facial bones and two bones in her right leg. Her ears are pierced. She has a scar on her left finger, a scar on her left cheek and scar on the fingertips of her left hand.

There is a long-standing history of domestic violence in their relationship. David was charged with her attempted murder in 1989 after he beat her with a pipe and Leone suffered numerous fractures. The charges were dropped after Leone refused to testify against him in court.

David was arrested for additional alleged domestic violence incidents in May 1997 and March 1999. He was also charged with child endangerment in January 1992. Leone continuously refused to cooperate with authorities and all domestic violence charges were eventually dropped against David.

Leone was last seen in Las Vegas sometime during February 2000. She left all of her personal belongings behind at her residence, including her clothes, money and vehicle. She has never been heard from again.

David never reported her as a missing person. He claimed that Leone was having an affair with a man named "Tim" and said that she left Las Vegas with him. One of Leone's family members alerted law enforcement about her disappearance in October 2000, eight months after she vanished.

Leone and David's seven-year-old daughter told authorities that she witnessed her parents having an argument the night before Leone disappeared. The child said that David pushed Leone through a plate glass window inside their residence, then smashed her head into their refrigerator.

It is believed that the fight revolved around David's belief that Leone was conducting an affair. Authorities stated that they located a male friend of Leone's in October 2000. Reportedly, David believed that she was romantically involved with the individual.

Investigators said that there was no evidence Leone and the man were having an affair. Officials are still attempting to verify the existence of "Tim."

The couple's home was searched in November 2000 and investigators announced they discovered evidence that suggested Leone did not leave of her own accord. Authorities said that foul play was suspected in her disappearance.

Drops of blood were located inside the couple's home and near Leone's vehicle. Investigators did not disclose whether the blood was identified as Leone's.



Vincent apparently took photographs of Marie performing sex acts and attempted to blackmail David with them prior to her disappearance. David was enraged by this. Vincent disappeared in November 1979. Fred Hackett, one of David's employees, later admitted he helped David dispose of Vincent's body.



She claimed that David forced her to move the body again several months afterwards. She said that he filled a 55-gallon drum with water and instructed her to haul water buckets while he poured cement over the gravesite.

Deloris attempted to lead law enforcement officials to the location, but she was unable to identify the site. She died of natural causes in 1987.


David hired an attorney after Leone's 2000 disappearance. He owns a furniture moving business in addition to the storage units. Authorities estimated that David was worth two million dollars in 2000.

In 2007, he was arrested and charged with Vincent's murder. The case was reopened after Fred Hackett told police he witnessed David murder Vincent and helped dispose of the body. Hackett's account of Vincent's murder is similar to Smith's account of David's confession.

The murder case against David was dropped in 2012, however, because Hackett had died and prosecutors couldn't prove David's guilt without his testimony.

Cowan, Marie and Leone's cases remain unsolved and charges have been not filed against anyone in connection with their disappearances, but David is considered to be the prime suspect in their cases.

Authorities don't believe Leone would have left of her own accord and abandoned her daughter, whom she was very close to. She also left behind a teenage son. Her body has never been found.
