Marie B. Morgan, 30, was last seen in Las Vegas, Nevada. She had sought help at a women’s shelter to escape an allegedly abusive marriage to David Dale Morgan; an employee of that shelter later reported her missing after Marie confided in them about the abuse. Marie’s disappearance is tied to a 1979 affair with Gabriel Vincent, who tried to blackmail David Morgan with explicit photos and then vanished in November 1979, seven months before Marie was last seen.

In 1985 David Morgan’s sister, Deloris Morgan, told investigators her brother had confessed to killing both Marie and Vincent. Deloris said David forced her at gunpoint to help move Marie’s body in 1980, first burying it along U.S. Route 95 past Indian Springs and later relocating it to a deeper grave covered in cement; she could not identify the exact location. Deloris died of natural causes in 1987. David has been a prime suspect in other disappearances and was arrested in 2007 on a Vincent-related murder charge that was dropped in 2012 after a key witness died.

Does anyone have information about Marie’s last known movements in Las Vegas or about burials along U.S. Route 95 past Indian Springs?
