Washington, DC Police Arrest Suspect in Lawyer's Murder

Body of David Messerschmitt found in a hotel room in February.

— -- Police in Washington, D.C., arrested a woman Wednesday in connection with the killing of a lawyer who was found stabbed to death inside a district hotel room.

Police didn't say what evidence led investigators to charge Gallmon but said they believe she was pictured in a surveillance video released by police.

The suspect is expected to make an appearance in court on Thursday.

Last week, Vuong asked for help finding her husband's alleged killer, saying she had lost her "husband and best friend."

"In one day, I lost the most important person in my life and the man I loved so much," she said.
