A woman has admitted posing as a man to lure a lawyer to a hotel, before stabbing him to death.

Jamyra Gallmon admitted killing David Messerschmitt by stabbing him repeatedly in the abdomen, groin and heart, in order to rob him of $40 (£26) in Washington DC in February.

The 21-year-old was arrested in April, and pleaded guilty to second-degree murder while armed at DC Superior Court.

Her 30-year-old victim had married his wife shortly before he died. He posted an ad on Craigslist looking for a same-sex hookup.

Messerschmitt was an intellectual property lawyer.

Planning to rob him, Gallmon responded to the Craigslist ad using the username chrissanchez0906.

Messerschmitt text his wife to say he would return home in an hour, while waiting in the Donovan Hotel.

After killing Messerschmitt, Gallmon told police that he had grabbed her arm during the robbery, and that she had a flashback to when she had been assaulted.

Messerschmitt’s body was found in the hotel room the following day. As well as the money, he was robbed of his Metro card.

Gallmon faces 18 to 25 years in prison.

In addition to Gallmon’s guilty plea, her 19-year-old roommate Dominique Johnson pleaded guilty to conspiracy to commit robbery.

Gallmon met Johnson after the incident, and the two walked hand-in-hand to the bus stop. Once on the bus, Gallmon told Johnson that “it went bad.”

Johnson faces a five-year prison sentence.
