When 30-year-old lawyer David Messerschmitt got a response to his Craigslist ad seeking some male affections outside his heterosexual marriage, he never could have expected the danger he’d be walking into.

Here are the details that show just how bizarre the case is: Messerschmitt went to meet “Chris Sanchez” at a hotel in Washington, D.C. in February, but little did he know that Sanchez was actually Jamyra Gallmon, 21, and her 19-year-old girlfriend Dominique Johnson posing as the fictitious gay man. The women used a photo of a male torso to seal the deal.

Gallmon entered Messerschmitt’s room at the unnamed hotel and attempted to rob him. We’d say “that’s when things went wrong,” but this whole mess was clearly wrong from the very beginning.

The young woman claims that Messerschmitt trapped her in the room, triggering a previous trauma from a past assault.

At least that’s the argument she’s using in court to try and explain how she came to stab Messerschmitt seven times in the abdomen, groin and heart, killing him.

She made it out of the room with $40 cash and Messerschmitt’s metro card, and walked hand-in-hand with Johnson to a bus stop. Housekeeping found Messerschmitt’s body the next day, his arms bound in rainbow-colored zip ties.

We have to wonder how Messerschmitt could have trapped Gallmon while his arms were bound, unless of course her story is completely made up.

And it would appear that it is, as she pleaded guilty to second-degree murder while armed in court on Thursday.

Gallmon faces 18 to 25 years in prison and Wilson up to five.
