In an affidavit in the case, ATF Special Agent Brendan Plasha wrote that the gang had operated "an open-air drug shop" in the block since at least 2012, with heroin as its primary product. Plasha wrote that, based on surveillance, the shop opens by 6:30 a.m. and "continues to operate non-stop throughout the day and into the early evening seven days a week," with about 10 drug transactions per hour.
