Herbert Tate, an HVAC technician, said he was walking in East Baltimore when Hersl and two other officers, Kevin Fassl and Sgt. John Burns, stopped him and searched him on the street. Hersl began checking nearby staircases and vacant homes looking for drugs before allegedly finding heroin stashed behind a wall. Tate said the drugs did not belong to him. Meanwhile, he said he had about $530 on him, and the officers reported submitting only about $220.
