Pruett, now 33, has been on Death Row at the Texas Department of Criminal Justice’s Polunsky Unit in Polk County since he was found guilty of capital murder on April 23, 2002, and sentenced to death.
His victim was 37-year-old TDCJ correctional officer Daniel Nagle.
The victim’s body was found in a pool of blood near the edge of a door to a multi-purpose room near a recreational area at the McConnell Unit on Dec. 17, 1999.
A homemade knife, described as an eight-inch, sharpened steel rod, was found near his body.
Nagle had worked for the TDCJ for only about three years when the murder took place.
He was president of the local 3890 correctional officers union at the time.
Pruett will be the second inmate executed for a murder committed in the McConnell Unit since it opened in the early 1990s.
The other inmate, Rogelio Cannady, was serving a life sentence for murder when, on Oct. 10, 1993, he killed his 55-year-old cell mate by beating him with a padlock in a sock.
He was executed in 2010.
