8 indicted after raids at Dallas adult bookstore, Plano home in deadly sex trafficking case, feds say

Eight people, including employees of a Dallas adult bookstore, have been indicted in connection with a sex trafficking investigation that left at least one victim dead, officials announced Tuesday.

The defendants have been identified as: 

• Montre Lamont Mason, also known as "Trey" or "Unc" 
• Eileen Mason, also known as "Mama" or "Ma" 
• Trelynn Love Mason, also known as "NuNu" 
• Aaron Tyrone Betford
• Larry Jones, also known as "Big Guy" 
• Krishenda Doss 
• Reginald Rose 
• Antonio Dario Osorio-Avelar

Six of the defendants were taken into custody on Friday, July 24, and 21 firearms were recovered, authorities said.

During a news conference, Travis Pickard, the special agent in charge of Homeland Security Investigations (HSI) Dallas, said for more than two decades, the bookstore "operated under the guise of a legitimate business while functioning as an illicit brothel."

For the past three years, multiple agencies have been involved in "Operation Midnight at Paris," which Pickard says revealed, "thousands of adults and minors were sold for commercial sex."

In one of those instances, Pickard said it led to the death of an Army veteran who had become a trafficking victim. The suspect in that case was sentenced to life in prison last year.

Defendants could face decades in prison

Ryan Raybould, who's the U.S. Attorney for the Northern District of Texas, said all eight have been charged with conspiracy to commit sex trafficking.

"On that charge alone, the defendants are facing decades in prison," Raybould said.

He said some of the defendants face additional charges that include sex trafficking through force, fraud or coercion, sex trafficking of a minor and conspiracy to launder money.

Adult bookstore, Plano home raided

According to the indictment, roughly, the crimes began in or around March 2020. 

The indictment states that Montre Mason, Eileen Mason, Trelynn Mason, Betford, Jones, Doss, Rose and Osorio-Avelar "knowingly conspired and agreed with each other and others... to recruit, entice, harbor, transport, provide, obtain, maintain, patronize and solicit by any means one or more persons," to benefit financially. 

Raybould said an investigation was launched by HSI Dallas' North Texas Trafficking Task Force. 

In February 2026, federal agents raided two locations – a home in Plano and the Paris Adult Bookstore, which was operated and managed by Montre Mason and Eileen Mason, in the 11000 block of Harry Hines Boulevard. Officials confirmed to CBS News that the two sites were tied to the same owner, Montre Mason, at the time. The couple is married. 

Authorities said that while the bookstore operated as a sexually oriented business, selling novelty items in the front of the store, the back of the store consisted of locked hallways and rentable rooms for commercial sex acts and human trafficking.

Raybould said that the adult bookstore employees, who included Trelynn Mason, Betford, Jones and Doss, allegedly would rent out the rooms and sell the alleged sex workers items from the store, including condoms, sanitary wipes and pregnancy tests.

Raybould said that the alleged "workers" who prompted a police response at the store were banned from the location by employees.

According to the indictment, Rose and Osorio-Avelar are accused of using the adult bookstore as a hub for sex trafficking victims.

Rose is accused of trafficking an adult victim, and Osorio-Avelar is accused of trafficking at least three minor victims.

Remembering the victims

Pickard said it's important to remember this case is about the victims.

"Investigators identified dozens of victims whose lives were forever changed by those who allegedly chose greed over human dignity," Pickard said. "Some survivors have begun the difficult journey toward healing. Others continue to carry the physical and emotional scars of their exploitation."

However, Pickard said that one of the victims, who hasn't been publicly identified, wasn't given that opportunity because she was allegedly kidnapped from the bookstore in 2024 and found "brutally murdered" by a commercial sex customer. The suspect in the case was identified, arrested and ultimately sentenced to life in federal prison.

Pickard said human trafficking "devastates communities."

He said this case sends an important message: "Criminal organizations can't hide behind storefronts, business licenses, or the appearance of legitimacy."

Dallas Police Chief Daniel Comeaux commended the work of the HSI, his department and the Texas Office of IRS Criminal Investigation, partnering together to bring justice in this case.

"There's no longer a Paris Bookstore," Comeaux said. "And we're going to make sure that Paris Bookstore does not come back."
