TUCSON, Ariz. — Earlier this month, a judge sentenced an Arizona man to 135 months in prison followed by five years of supervised release for possessing to distribute methamphetamine and possessing a firearm as a convicted felon. Homeland Security Investigations (HSI), the FBI, and the Drug Enforcement Administration conducted the investigation in this case.

Sean Lee Arnold, 51, of Tucson, previously pleaded guilty to possession with the intent to distribute methamphetamine and possession of a firearm by a convicted felon.

“Some might argue that a convicted felon would have learned their lesson and not further and intentionally engage in illegal activity,” said HSI Arizona Special Agent in Charge Scott Brown. “However, in this particular case, the defendant decided to do the opposite. HSI and our partner agencies will not stand by while criminals believe they will not be caught. This lengthy sentence is a result of our resources coming together to provide safe neighborhoods for the people of Arizona.”

On Aug. 31, 2021, law enforcement agents served a search warrant on Arnold’s home in central Tucson and found approximately 1.35 kilograms of pure methamphetamine and a rifle. Arnold admitted to agents that he bought and sold multiple pounds of methamphetamine a month and that he knew he was prohibited from possessing weapons.
