"Long before Erika Menendez was charged with pushing a stranger to his death under an oncoming train at a Queens elevated station..."

"... she had years of contact with New York City’s mental health and law enforcement establishments."

She was treated by the psychiatric staffs of at least two city hospitals, and caseworkers visited her family home in Queens to provide further help. She was also arrested at least three times, according to the police, twice after violent confrontations....

There were ample warnings over the years concerning Ms. Menendez.

In 2003, according to the police, she attacked another stranger, Daniel Conlisk, a retired firefighter, as he took out his garbage in Queens.

“I was covered with blood,” Mr. Conlisk recalled on Sunday. “She was screaming the whole time.”

That's the NYT. In The Daily News, we learn that what she was screaming was "You fucked my mother."
