Two teenage girls, ages 13 and 15, have been arrested and charged with second-degree murder in connection with the fatal beating of 64-year-old Reginald Brown in Northwest Washington in October. They are part of a group of girls who assaulted Brown, resulting in his death. The case involves a total of five girls who were initially charged, with three facing upgraded first-degree murder charges. The trial for the first three suspects is scheduled for August. Additionally, two more teenage girls have recently been arrested in connection with the same incident and charged with second-degree murder, as the investigation continues.
