An explosion and fire forced more than a hundred seniors to evacuate in Bowie Tuesday morning. No one was hurt, but it caused the building to partially collapse. Now, the vulnerable residents don’t know where they’ll go. WTOP’s John Domen heard the blast and went straight to the scene. He tells what happened and what concerns the residents’ loved-ones. And many of us are looking forward to a long weekend to honor Juneteenth. Derrick and Ramunda Young, who own Mahogany Books, are celebrating the holiday by renewing their vows and throwing a street celebration in honor of Emancipation Day.
