Joey Poindexter, the Gaithersburg man convicted of sexually assaulting five young men he met at beer-pong events, victimized at least 25 others, prosecutors said in court papers filed this week ahead of Poindexter’s sentencing.

The 40-year-old faces up to 200 years in prison for the assaults on the five victims. His sentencing began with a brief hearing Friday morning and is scheduled to conclude with a second hearing next month.

All five victims had been drinking and said they did not consent to sex. Prosecutors suggested in the new court papers that they may have been drugged, as well.

Poindexter “ensured that his victims were incapacitated,” Montgomery County assistant state’s attorneys Timothy Hagan and Patrick Mays wrote, “either through alcohol or a combination of alcohol and another substance. Once he confirmed they were helpless, he violated them sexually in every way imaginable, and often recorded it as keepsake.”

Poindexter was found guilty in two trials earlier this year. Three of the victims testified. Part of the time they found themselves answering questions directly from Poindexter while he acted as his own lawyer. All five victims have felt the “severe, traumatic and continued devastating” effects of Poindexter’s assaults, Hagan and Mays wrote in court papers

Poindexter, who worked as a real estate appraiser, photographed and videotaped many of his encounters. An analysis of his cellphone and digital media storage devices revealed numerous other victims, prosecutors said. “The defendant documented and catalogued a staggering 30 victims of his sexual assaults,” the prosecutors wrote.

Prosecutors said there could be other victims whose encounters with Poindexter were not found on the phone or digital media. They are requesting the maximum sentence in the case — 200 years — but said state sentencing guidelines call for 108 to 157 years.

In court Friday morning, the mother of one of the victims spoke to Montgomery County Circuit Court Judge Richard E. Jordan, saying that Poindexter took advantage of a young man who was looking for a mentor. Her son has become isolated and does not want to talk about what happened, she said.

Jordan told her to pass along his concern and thanks to her son, who testified at one of Poindexter’s trials.

“If you would tell him that I said to you that I would encourage him to get some counseling, and if you would tell him that I think what he did was an act of bravery,” said Jordan, who added that many people would not have had the courage to testify.

“He gave a gift to the community,” Jordan told the young man’s mother.

At one point, she tried to get the attention of Poindexter, who was in the courtroom.

“You don’t want to look at me?” she asked him.

Jordan postponed the balance of the hearing until April 15. Poindexter recently retained an attorney, Rebecca Nitkin, and she had requested time to study the case.

Nitkin said she is concerned that sentencing guideline’s range, as asserted by prosecutors, is too high. She said she is representing Poindexter pro bono, because he previously fired attorneys provided to him by the county’s public defender’s office.

“Everyone deserves a defense,” Nitkin said.
