Lawyer's Washington, DC, Hotel Stabbing Death Puzzles Investigators

Surveillance footage shows a person of interest in a hooded jacket and gloves.

The body of David Messerschmitt, 30, was discovered Tuesday inside the Donovan, with multiple stab wounds.

Surveillance footage shows a person of interest in a hooded jacket and gloves, pacing in front of a lobby elevator, then climbing the stairs -- before eventually getting out on the same floor where Messerschmitt’s body was discovered.

Metropolitan Police Department Chief Cathy Lanier said police are investigating numerous angles.

“We really have no idea what the motive is at this point, so everything is open,” Lanier said.

Messerschmitt’s family pleaded for the community’s help in a statement.

“Someone out there knows something, and we hope they come forward to help the investigation,” the family's statement read.
