Brownstone Lane murders

In April 2022, a judge in the 351st District Court was expected to sign Brown's death warrant, who had exhausted all of his appeals. In May 2022, prosecutors and defense attorneys attempted to sway a Harris County judge to decide on Brown's death warrant. Prosecutors attempted to sway the judge to set an August 31 execution date for Brown, while his lawyers argued he had an intellectual disability and was therefore ineligible for execution. On May 20, the judge declined to sign the death warrant for Brown, prompting an angry reaction from family members of the victims. Following the verdict, a Harris County District Attorney's prosecutor announced they would challenge the judge's decision through the Court of Appeals.

On August 17, 2022, the same judge who initially declined to sign the death warrant in May, signed Brown's execution warrant, with the execution date set for March 9, 2023.

Brown has repeatedly attempted to appeal his conviction. In August 2014, Brown lost a federal court appeal after arguing he should be provided $7,500 to pay for a mitigation specialist to assist him with his clemency petition. A federal district court refused, and the 5th U.S. Circuit Court of Appeals upheld the lower court's rejection. In October 2017, Brown lost another appeal when the Texas Court of Criminal Appeals denied him a new trial or new sentencing phase.

Dudley was executed by lethal injection at the Huntsville Unit in Huntsville, Texas on January 25, 2006. Brown remains incarcerated on death row at the Allan B. Polunsky Unit and is scheduled for execution on March 9, 2023. Dunson remains incarcerated at the Huntsville Unit and is eligible for parole in 2027.

Dudley was executed by lethal injection on January 25, 2006, in Huntsville, Texas. He became the first person to be executed by the state of Texas in 2006.

Marion Butler Dudley was also convicted of capital murder and was the second of the three perpetrators to be convicted. On January 23, 1995, he was sentenced to death.

Arthur "Squirt" Brown Jr. (unrelated to victim Audrey Brown) was convicted of capital murder. In November 1993, he was sentenced to death. He was the first of the three perpetrators to be convicted. As of May 2022, he was still on death row.

The Brownstone Lane murders were the mass murders of four people at a residence in the 4600 block of Brownstone Lane in Houston, Texas. On June 20, 1992, three men tied up six people and shot all of them in the head execution-style. Four of the six victims died. The perpetrators: Marion Butler Dudley (May 13, 1972 – January 25, 2006), Arthur "Squirt" Brown Jr. (born August 14, 1970), and Antonio "Tony" Lamone Dunson (born November 7, 1972) were convicted of capital murder. Dudley and Brown were sentenced to death, while Dunson was sentenced to life in prison.

On June 20, 1992, four people were shot and killed during a drug deal at a residence in the 4600 block of Brownstone Lane in Houston, Texas. Marion Dudley, Arthur Brown Jr., and Tony Dunson had gone to the home of Jose and Rachel Tovar to buy three kilograms of cocaine when they decided to rob them of their drugs and money. Six people were bound and shot by the trio inside the home. By the time police arrived, three victims were dead: Jose Tovar, Jessica Quinones (seven months pregnant), and Frank Farias. Of the three survivors, one, Audrey Brown, later died in a hospital, making the total number of murder victims four. The remaining two survivors identified Marion Dudley, Arthur Brown Jr., and Tony Dunson as their attackers.

On July 8, 1992, Dudley and Dunson were captured at a mobile home in Fayetteville, North Carolina. On October 23, 1992, Brown was captured by members of the Tuscaloosa County Metro Homicide Unit at an apartment in Northport, Alabama.
