Notable Case Summaries:
Antwan Lamont Shackelford:
From at least February 2023 through March 29, 2023, Shackelford conspired with his co-defendant to distribute 107.3 grams of pure methamphetamine throughout the Southern District of Indiana, with Shackelford serving as the supplier. Shortly after completing a drug transaction, IMPD officers conducted a traffic stop and arrested both men. During processing at the Marion County Jail, Shackelford was found to be concealing two baggies—8.355 grams of pure methamphetamine and 2.47 grams of fentanyl—in his anal cavity.

On August 6, 2024, Reyes‑Dominguez was traveling on I‑465 to deliver drugs to a customer in Frankfort, Indiana, when he was stopped by law enforcement officers. He was accompanied in the vehicle by his two‑year‑old daughter, his wife, and his mother. A search of the vehicle uncovered 430.5 grams of pure methamphetamine, 43.1 grams of cocaine, packaging materials, a metal grinder, and a Glock 19X 9mm handgun loaded with seventeen rounds. The methamphetamine and cocaine were found inside his daughter’s diaper bag.
In a subsequent statement to law enforcement, Reyes‑Dominguez admitted that he had paid approximately $9,000 to cross the border and enter the United States illegally. As part of his guilty plea, he acknowledged that he will be subject to removal from the United States upon completion of his sentence and must surrender to U.S. Immigration and Customs Enforcement upon release.
