Background

Ronald Dickey Mason was charged with drug offenses and a firearm offense. He pleaded guilty to the drug charges but went to trial on the firearm charge. A jury found him guilty of carrying a firearm during a drug trafficking crime.

The court’s reasoning

The court reviewed the sufficiency of the evidence de novo and found a reasonable jury could infer the defendant knew of the firearm in his car and carried it in furtherance of drug trafficking. Regarding the character evidence claim, the court found no plain error because the witness referred to drug traffickers generally, the defendant had already pleaded guilty to drug offenses, and the evidence of guilt was strong.

What it means going forward

The decision reinforces that proximity and accessibility of a firearm in a vehicle used for drug trafficking can support a conviction under federal law.
