Sgt. Anna Rose with U.S. Park Police confirmed that other, similar graffiti has been found in several places in Downtown D.C.
Vandals left similar writings on a utility box on 15th Street, another utility box near Roosevelt Island, and on a stop sign near the Sylvan Theater, which lies on the grounds of the Washington Monument, said Mike Litterst, spokesman for the National Park Service.
A WTOP listener vacationing in Boston over Presidents Day said he spotted what looked like the same graffiti on a mailbox there.
Litterst said investigators were already aware of graffiti left on a utility pole in Boston that was shared on Twitter on Jan. 26.
Other Twitter users replied that they had seen the same thing in other parts of Boston.
Rose said her department has been in touch with Boston police about several leads, and that the investigation is ongoing.
The Lincoln Memorial, the Washington Monument, the World War II Memorial and the D.C. War Memorial were each found defaced over the Presidents Day weekend. Workers began removing the graffiti on Tuesday.
