Diana L. Leone, 35, was last seen in Las Vegas on February 14, 2000. A white female with red/auburn hair and hazel eyes, she was about 5 feet 5 inches tall and 120 pounds. At disappearance she was reportedly wearing blue jeans, a white T-shirt, and a watch on her right wrist, and had identifiable scars on her left cheek, a finger of her left hand, and on the fingertips of that hand.

Leone lived in Las Vegas with her longtime boyfriend, David Dale Morgan, and their children. Court records and media accounts describe a documented history of domestic violence between them; one report says a child described a violent argument between Leone and Morgan shortly before she vanished. She left behind personal belongings, money, clothing, and her vehicle, and had no contact with friends or family after February 14, which family members later found highly unusual.

Investigators reportedly found evidence in the residence and have publicly identified Morgan as the primary suspect, but no criminal charges have been filed in connection with her disappearance. Allegations have also linked Morgan to other unresolved disappearances; detectives have explored those leads while keeping Leone’s investigation open. DNA reference samples from family have been submitted to assist future identification efforts.

If anyone knew Diana, her routines, or saw her in Las Vegas around mid-February 2000, please share what can help bring clarity to this case.
