Suspect in pregnant teen death had baby obsession

The woman wasn't comfortable with that and a jitney was called for Curry-Demus in the early morning of May 5. While the woman was looking out the window for the jitney, Curry-Demus grabbed her from behind and stabbed her in the back. Curry-Demus fled when the woman called for her husband.

Hours later, Curry-Demus visited another hospital and met a young mother whose 3-week-old baby was being treated for meningitis. The next day--May 6--several nurses saw Curry-Demus at the hospital and later noticed the baby was missing.

Police located Curry-Demus by tracing calls made from the hospital to Curry-Demus' mother. The baby was recovered unharmed.

Curry-Demus pleaded guilty in January 1991 to kidnapping, concealment of the whereabouts of child and related offenses and was sentenced to 3 to 10 years in state prison for taking the baby from the hospital. She also pleaded guilty to aggravated assault in the stabbing case and received 10 years' probation. She was released in 1998.

While awaiting resolution of the 1990 cases, Curry-Demus was twice briefly committed to a state mental hospital. An examination found her to be "in the midst of a major depressive episode." She also reported auditory hallucinations--that she kept "hearing babies cry."

She was found competent to stand trial, but also diagnosed with major depression and a mixed personality disorder. She graduated high school, but tests showed she had a "borderline intelligence level."

Johnson's funeral will be Friday in McKeesport, her family announced. In obituary information provided by a funeral home, the family said Johnson volunteered with the Salvation Army, helping with the homeless and day care.

The family has named her son after her: Terrell Kian Johnson.
