Six central Indiana residents have been sentenced to federal prison after separate drug investigations tied to methamphetamine, fentanyl, cocaine, heroin, firearms, ammunition, digital scales, and large cash seizures.
The U.S. Attorney’s Office for the Southern District of Indiana said the prosecutions were resolved in March or April 2026. Sentences ranged from 10 years to 20 years, with several defendants also receiving supervised release after prison.
Antwan Lamont Shackelford, 46, of Indianapolis, received the longest sentence, with 20 years in federal prison and 10 years of supervised release. His conviction involved conspiracy to possess with intent to distribute and distribute 50 grams or more of methamphetamine.
Joshua Richey, 43, of Indianapolis, was sentenced to 15 years in prison and eight years of supervised release for controlled substance and firearm convictions. Derrick Anthony Griffin, 50, also of Indianapolis, received 10 years and 10 months for cocaine and fentanyl convictions.
Three others received 10-year prison terms. Wilfredo Alexander Reyes-Dominguez, 26, of Hamilton County, Carlos Bullock, 27, of Indianapolis, and Aaron Burk, 50, of Brazil, Indiana, were sentenced in cases involving methamphetamine, firearms, or possession with intent to distribute.
Investigators reported several drug seizures across the six federal cases, including 124 grams of fentanyl, 291 grams of fentanyl analogue, 491 grams of methamphetamine, and 188 grams of heroin. They also recovered 1.3 grams of black tar heroin.
The remaining seized substances included 73.5 grams of cocaine and 127 grams of a substance containing marijuana. The variety matters because these cases were not limited to one drug type, but also involved multiple substances tied to separate trafficking and possession convictions.
Authorities also found three guns, assorted ammunition, digital scales, and more than $285,000 in cash set for forfeiture. Those items often strengthen trafficking cases because they can show distribution activity, weapon access, and money tied to drug movement.
These sentences matter because the cases were separate, but the pattern is similar: drug trafficking tied to firearms, cash, and larger distribution activity. Federal prosecutors often focus on that combination because it suggests more than simple possession or low-level sales.
The investigations also show how local and federal agencies are working together across central Indiana. Indiana State Police, Clarksville Police Department, Indianapolis Metropolitan Police, and the Metro Drug Task Force all assisted, giving prosecutors stronger cases across different jurisdictions.
Supervised release also matters after prison time ends. Several defendants received years of monitoring after their sentences, which keeps federal oversight in place and gives authorities another tool if someone violates conditions or returns to trafficking activity.
These Indiana cases keep the debate focused on whether long federal sentences can slow trafficking when drugs, firearms, and large cash seizures appear together. Supporters see prison time as necessary, while critics argue supply often adapts unless prevention and treatment keep pace.
What comes next is likely more coordination between federal prosecutors and local agencies across Indiana. With fentanyl, methamphetamine, cocaine, and firearms still central to major cases, investigators will keep watching distribution patterns while courts use supervised release to extend oversight after prison.
