A Belmont woman accused of trying to kill an elderly dementia patient at a Cambridge hospital was ordered held without bail Wednesday in Cambridge District Court.

Tania Boghossian, 53, is due for a mental health evaluation and scheduled for a next hearing in court Nov. 15, Judge Dominic Paratore said.

The apparent murder attempt took place in a Cambridge hospital Oct. 12, authorities said, which was several days after a man in his 80s had been admitted to the hospital as a result of complications from dementia. Boghossian had been staying with the victim in his room since his hospital admission.

According to reports, a sitter was assigned by the hospital to watch the victim during his stay. At approximately 2 p.m., the sitter told hospital personnel that the victim and Boghossian were behind a curtain in the hospital room when he heard Boghossian say, “Take your last breath.” The sitter drew the curtain and saw her holding a pillow over the victim’s face, according to District Attorney Marian Ryan’s Office.

Hospital security were contacted and removed Boghossian from the premises. 

Cambridge Police were told by the Middlesex District Attorney’s Office of the incident Oct. 18; a warrant was issued for Boghossian’s arrest after an investigation.
