What Did Roy Alan Stuart Tell Kent McGowen? Comparing Public Records to Alleged Prison Confessions
By Investigative Reporter Tammy Rose
For decades, investigators, journalists and law enforcement agencies have documented Roy Alan Stuart’s criminal history and alleged connections to unsolved murders across Texas.
Years later, former Harris County deputy Joseph Kent McGowen says Stuart discussed many of those crimes while the two were incarcerated together at the Duncan Unit of the Texas Department of Criminal Justice.
This investigation compares McGowen’s interview with historical newspaper articles, court records and investigative records to separate information that was already part of the public record from allegations McGowen says Stuart shared privately in prison.

What Public Records Already Documented
Historical newspaper articles, court records and investigative files already linked Roy Alan Stuart to numerous investigations before McGowen’s interview.
Terri Denise McDaniels, 26, was found dead near Pearland on Nov. 5, 1986. She worked out of Houston’s LaMonte Hotel. Investigators determined she died from strangulation or suffocation, and her homicide remains unsolved.
Historical reports state friends last saw McDaniels leaving the LaMonte Hotel with a white man driving a small, light-blue station wagon.
Less than five months later, investigators found Carolyn Sosa dead in Bastrop Bayou. Like McDaniels, Sosa frequented the LaMonte Hotel and died from strangulation. Historical records identify Sosa as one of the witnesses interviewed during the McDaniels investigation.
Investigators later focused on Roy Alan Stuart in both cases. Records show witnesses identified Stuart as the man who picked up both women, and investigators found Sosa’s fingerprints and hair inside his car. Prosecutors charged Stuart in both murders, but a judge later dismissed the charges. Both homicides remain unsolved.
McGowen also described several additional investigations during his prison interview. Some of those claims could not be independently matched to historical records.

Potter County Nun Investigation
Historical records already identified Roy Alan Stuart as a suspect in the Potter County nun investigation.
McGowen says Stuart later described the case to him in prison and claimed he concealed the victim beneath an overturned cattle trough before investigators eventually returned him to the scene.

Telephone Road Account Compared to Public Records
A July 2023 text message reviewed by Investigative Reporter Tammy Rose shows former Brazoria County investigator Matt Wingo believed the woman McGowen described during his Telephone Road account was Carolyn Sosa.
According to McGowen, Stuart claimed he picked up a Black woman dressed as a cowgirl during the Houston Livestock Show and Rodeo along Telephone Road before taking her to Brazoria County.
McGowen said Stuart described sexually assaulting the woman, attempting to strangle her with a seat belt before shooting her with a .22-caliber pistol. He also claimed Stuart said a fisherman witnessed the attack from a nearby boat.
Friends told investigators they last saw her leaving the LaMonte Hotel with a man driving a small, light-blue station wagon. Prosecutors later charged Roy Alan Stuart after witnesses identified him as the man who picked up Sosa and investigators found her fingerprints and hair inside his car.
Prosecutors later dismissed the murder charge.
McGowen also described additional details that do not appear in the historical records reviewed for this story.

Alleged Murder-for-Hire Involving a Deputy Constable
McGowen claimed Stuart said someone paid him about $3,000 to kill a deputy constable.

McGowen’s handwritten notes also contain the entry:
“Lived w/ BC Constable & family from ’82-’84 yrs.”
The notebook does not identify the deputy constable or explain whether that notation relates to the alleged murder-for-hire.

Comparing McGowen’s Account to Public Records
Comparing McGowen’s interview with historical records reveals two distinct categories of information.
Many of the investigations discussed—including Carolyn Sosa, Terri McDaniels, Linda Kay Simmons and the Potter County nun investigation—were already documented through historical reporting, court records and investigative files before McGowen’s interview.
Other allegations, including the deputy constable murder-for-hire, the Tomball account, the Brazos River disposal site, the alleged first homicide at age 10 and several other prison stories, were not located in the historical records reviewed for this comparison.
