While trick-or-treaters begged for candy Tuesday, undercover police set up a deal to trade crack cocaine for handguns at a Hillyard home where two teens were murdered last summer.
After the trade, authorities arrested two suspects, including the brother of a teenage girl wounded in the August shooting spree.
Eric D. Denny, 18, and Ganyn Matthews, 19, are charged with selling crack cocaine and possessing a 9mm pistol during a drug deal.
