BPD allowed scene cleanup soon after Brooklyn Homes mass shooting. But was key DNA evidence tossed?

The morning after the worst mass shooting in recent Baltimore history, cleaners with red dustpans and brooms worked behind police tape on Elarton Court, sweeping trash. An hour later, a Baltimore Police Department employee began laying down evidence markers. Even casual viewers of TV cop dramas might be surprised by this order of operations — and forensic experts interviewed by The Banner were too. Cleaning a crime scene before police finish processing evidence goes against national standards, they said.
