PITTSBURGH (AP) — A mother accused in Pittsburgh of deliberately injecting her 4-month-old son with salt water will be sent to a state mental hospital because she suffers from severe depression.

Amber Brewington, 21, of Duck River, Tenn., appeared Thursday in court via videoconference for a competency hearing. Allegheny County Judge Jeffrey Manning ordered that Brewington be sent to Mayview State Hospital for no more than 90 days.

Psychiatrist Christine Martone testified that Brewington needs to be tested for Munchausen by proxy syndrome, in which a caregiver fakes or induces illness in others to generate sympathy. Martone says Brewington also has a borderline personality disorder and admits to having suicidal thoughts.
