Police said John Heilmeier, 57 of the 100 block of Anderson Highway in Cumberland, Va. and Richard Summers, 64, of the 10700 block of Cedarwood Drive in Waldorf were apprehended Friday, Jan. 11 by the county's Firearms Interdiction Team for selling the illegal magazines at a knife and gun show taking place Jan. 11-13.
"It is critical to have effective laws regarding high capacity magazines, and it is equally important for those involved in the sale of firearms and related equipment to conduct their business in a responsible and law-abiding fashion," Baltimore County Police Chief Jim Johnson, who chairs the National Law Enforcement Partnership to Prevent Gun Violence, said in a statement. "These laws are in place to protect public safety, and violations such as this endanger the community."
According to police, an undercover detective saw a pair of customers ask one of the two vendors for a magazine compatible with a .223 caliber AR-15 rifle.
Police said the customers were sold what appeared to be a 30-round magazine and after interviewing the detectives, police confirmed the magazine was illegal and then confiscated it.
According to Maryland law, magazines that hold over 20 rounds cannot be sold or purchased, county police said.
Later that day, the detectives approached the vendor and asked to purchase a 30-round magazine. Police said the vendor told he could not say "30-round magazine" in Maryland, but that the magazine could be purchased.
Detectives purchased a pair of magazines labeled as 20-round clips, but police said they were determined to hold 30 rounds.
Both men were arrested and charged with a firearms violation and released on their own recognizance, police said. A trial has been set for Tuesday, May 14.
