The woman arrested in connection with spattering city landmarks with green paint last month has been moved from a half-way house to a psychiatric ward, her attorney said Thursday during a hearing in D.C. Superior Court.

Judge A. Franklin Burgess Jr. ordered another hearing Sept. 18, for 58-year-old Jiamei Tian, who is charged with one count of defacing property. She was arrested July 29 at Washington National Cathedral shortly after authorities discovered paint on an organ in the Bethlehem Chapel and in the cathedral’s Children’s Chapel.

Authorities have said Tian, who they believe is homeless, is a suspect in the vandalism in which green paint was used to mar the Lincoln Memorial, a statue next to the Smithsonian Castle on the Mall and two places at Thomas Circle, Luther Place Memorial Church and a statue of Martin Luther.

A judge earlier this month ordered Tian freed from custody and into the half-way house. At Thursday’s status hearing, Tian’s attorney, Nancy Glass from the Public Defender Service, told Burgess that doctors who had evaluated her client on Wednesday grew concerned about her mental state.

Tian was moved to the psychiatric ward at MedStar Washington Hospital Center, Glass said. Tian, who appeared in a previous court appearance with a Mandarin interpreter, was not in court Thursday.
