Police arrested a second woman connected to the brutal murder of David Messerschmitt, a 30-year-old lawyer who was found stabbed to death in a Thomas Circle Hotel room on February 9. Metropolitan Police arrested 19-year-old Dominique Johnson Wednesday at 7:45 a.m. The young woman was charged with conspiracy to commit robbery. Police refused to elaborate on Johnson’s role in the crime. Last week, police arrested 21-year-old Jamyra Gallmon, and charged her with first-degree murder. According to a criminal complaint, Gallmon arranged to meet Messerschmitt through a Craigslist advertisement with intentions of robbing him. Messerschmitt’s spouse, Kim Vuong, had reported him missing and his body was discovered by hotel staff the next day. Her defense attorney pleaded not guilty, claiming the incident was “an imperfect self-defense.” Court records indicate that Gallmon and Johnson were in court together last month disputing a landlord-tenant issue as police were investigating Messerschmitt’s death. Johnson is scheduled to appear in D.C. Superior Court on Thursday.
