David Martin Caldwell, 52, was shot and killed the morning of July 15, 2019 while working at the Man Alive methadone clinic on Maryland Avenue in Baltimore. A phlebotomist by trade, Caldwell had worked at the clinic for several months and his family described him as compassionate and devoted to helping people in recovery. He had expressed concerns about his safety at work and had hoped for a closer parking spot to avoid walking in the dark.

According to police, 49-year-old Ashanti Pinkney entered the clinic armed with a .357 magnum revolver not registered to him. The encounter escalated into an active shooter situation; officers, including Baltimore Police Sergeant Bill Shiflett, arrived and were shot at during the response. Body camera footage shows officers repeatedly ordering Pinkney to drop his weapon before gunfire was exchanged. Pinkney was shot and killed at the scene, and no arrests were made in Caldwell’s killing because the shooter died there.

Caldwell’s friends and family mourned him as someone who cared for others and was killed while assisting people striving to improve their lives. Does anyone have information about Caldwell’s work at the clinic or the events that morning?
