Marion Albert Pruett (October 4, 1949 – April 12, 1999)[2][3] was an American serial killer.

Pruett later claimed that he had perpetrated the prison murder, contradicting his previous testimony for which he had received federal protection.

Pruett killed Peggy Lowe after he kidnapped her on September 17, 1981, while robbing the Metrocenter Branch of Unifirst Bank (later Trustmark National Bank) in Jackson, Mississippi where she worked; Bobbie Jean Robertson, a convenience store clerk in Fort Smith, Arkansas; and Anthony Taitt and James Balderson, two convenience store clerks in Colorado.

On trial in New Mexico for the March 2, 1981, murder of his common-law wife, Pamela Sue Barker (aka Michelle Lynn Pearson), Pruett admitted he had robbed her in order to support a $4,000 a week cocaine habit, but denied that he killed Barker, who was beaten to death, then set on fire.

[4] From death row, he asked a Mississippi newspaper to pay him $20,000 to disclose the location of Barker's engagement ring, and offered to reveal the location of a Florida victim's body in exchange for a paid appearance on Geraldo.
