UNITED STATES OF AMERICA Criminal Action No. 25-31 (BAH)

Judge Beryl A. Howell

ADRIAN THOMPSON,

Defendant.

MEMORANDUM OPINION

The government’s pending motion to dismiss without prejudice the indictment against defendant Adrian Thompson amounts to nothing more than a strategic attempt to circumvent the Speedy Trial Act in circumstances where noncompliance with this statute was inevitable and due entirely to the government’s own mismanagement of this case. After defendant was first arrested in 2024 and brought to the District of Columbia Superior Court, the charge against him was “no-papered,” or declined for prosecution, but then he was arrested a second time in 2025 and charged in this Court and scheduled to face a jury trial on July 20, 2026, on a one-count indictment alleging felon-in-possession of a firearm, in violation of 18 U.S.C. § 922(g)(1). See Indictment, ECF No. 1; Scheduling Order (Mar. 17, 2026). Following a series of missteps by the U.S. Attorney’s Office for the District of Columbia (“USAO-DC”)—including double booking its line attorney for two trials scheduled to begin on the same day; knowing for over nine months about problems with an essential government witness but failing to make timely alternative plans; and ignoring defendant’s repeated requests for discovery and Brady materials—the government realized in the lead up to the trial date, which had been proposed by the parties and adopted by the court four months earlier, that it is not ready. After first attempting to seek a continuance of “at

least 90 days,” Gov’t’s Opposed Mot. to Continue Trial at 1 (“Gov’t’s Mot. Continue”), ECF No. 51, which was denied on Speedy Trial Act grounds, the government is now requesting dismissal without prejudice pursuant to Federal Rule of Criminal Procedure 48(a). See United States Mot. to Dismiss Indictment Without Prejudice (“Gov’t’s MTD”), ECF No. 67.

The missteps leading to the current posture of this case may be laid squarely at the feet of management at the USAO-DC. How else to explain double-booking the same Assistant U.S. Attorney (“AUSA-1”) for two jury trials on the same day in this Court, without substituting in another line attorney for one of the trials? How else to explain that the assigned AUSA-1 needed supervisory permission to call the essential law enforcement witness necessary for the introduction of DNA evidence tying defendant to the gun at issue in the charge, yet was not alerted of that requirement by his supervisors until less than a month before trial? How else to explain that when supervisors were consulted by another AUSA (“AUSA-2”) about the witness problem in mid-June 2026, efforts to re-do the DNA testing by collecting new buccal swabs from defendant did not occur until almost four weeks later at the pretrial conference held ten days before the scheduled trial date? How else to explain the recurring problems involving the same essential government witness in USAO-DC cases, including a prior case in this Court where the same issue also surfaced just before trial?

The present predicament boils down to this: The government cannot proceed to trial due to its own dilatory behavior and so grasps at Rule 48(a) to end-run the Court’s denial of its continuance motion. The government has informed the Court that, after dismissal, it will be ready to re-prosecute “in approximately 90 days” at which time “this case can proceed to adjudication.” Gov’t’s Reply in Supp. of MTD (“Gov’t’s Reply”) at 7, ECF No. 71. Unsurprisingly, defendant, who has met nearly every court-imposed deadline, been under stringent pretrial supervision for

over a year, and diligently prepared for months in reliance on the parties’ jointly proposed July 2026 trial date, vigorously opposes the government’s motion and requests instead dismissal with prejudice. See Def.’s Opp’n to Gov’t’s MTD and Request for Dismissal with Prejudice (“Def.’s Opp’n”), ECF No. 70. For the reasons set forth below, the government’s motion for without-prejudice dismissal is granted in part insofar as the motion seeks dismissal of the indictment, and denied in part as to its request that the dismissal be without prejudice. Accordingly, the indictment against defendant is dismissed with prejudice. I. BACKGROUND The factual and procedural background relevant to resolving this motion to dismiss is described below.

A. Factual Background The factual background of this case has already been described in detail in a previous opinion denying defendant’s motion to suppress tangible evidence. See United States v. Thompson, No. 25-cr-31 (BAH), 2026 WL 1917109, at *1-2 (D.D.C. July 3, 2026). Only the basic facts, as alleged by the government, relevant to understanding the pending motion to dismiss the indictment are summarized here.

On June 1, 2024, at around 11:18 p.m., two members of the Metropolitan Police Department’s Robbery Suppression Unit, Sergeant Scott Possinger and Investigator Wilfredo Guzman, observed from their patrol vehicle a blue Audi parked in a parking lot directly in front of 323 53rd Street, NE, Washington, D.C. Id. at *1. As they pulled their patrol vehicle up to the parking lot, an individual (later identified as Dion Dempsey) exited from the driver’s side and another individual (later identified as defendant) exited from the front passenger’s side. Id. Dempsey and defendant both walked away from the parked Audi and the patrol vehicle toward a group of people standing in the apartment courtyard abutting the parking lot. Id. As Dempsey and

defendant walked away, the officers parked, exited their patrol vehicle, and approached the Audi to investigate. Id.

Sergeant Possinger shone his flashlight at the partially open window of the driver’s side, and observed on the floor, partially under the driver’s seat, a “large,” “clear” Ziploc bag containing suspected marijuana exceeding two ounces, the legal limit for recreational marijuana consumption. Id. at *2 (citing Suppression Hearing Transcript (May 28, 2026) (“Suppression Hr’g Tr.”) at 28:13- 18, 23-25, ECF No. 48). Sergeant Possinger remarked to his colleague that there was “a bunch of weed” in the Audi, and asked Dempsey to “com[e] over here” and “talk.” Id. (citing Suppression Hr’g, Gov’t’s Ex. 1, Possinger Body-Worn Camera Clip (“Possinger BWC”) at 23:19:14-28).

Sergeant Possinger told Dempsey that because there was “more than 2 ounces of marijuana . . . [u]nder the seat,” he was “going to search [the] vehicle.” Id. (citing Possinger BWC at 23:19:36-46). Dempsey protested the search, and Sergeant Possinger heard Dempsey say, “No, I ain’t got no weapons” in there. Id. (citing Possinger BWC at 23:19:44-46; Suppression Hr’g Tr. at 84:6-8). Dempsey also told Sergeant Possinger that his aunt was the registered owner of the vehicle, walking away from Sergeant Possinger to “get her.” Id. (citing Possinger BWC at 23:20:00-05). Later investigation revealed that Dempsey was the registered owner of the vehicle. Id. As Sergeant Possinger opened the vehicle door to begin his search of the interior, he observed Dempsey “running” away. Id. (citing Possinger BWC at 23:20:20). Dempsey was subsequently arrested, and a search of the interior revealed a digital scale under the driver’s seat with the marijuana, and a firearm in the glove box compartment. Id.
