Parole bigs were warned ‘Brooklyn ripper’ was dangerous

Daniel St. Hubert’s parole officer told cops she warned her bosses that the alleged kid killer was dangerous and needed to be in a mental hospital — but nothing was ever done, The Post has learned.

Officer Roxanne Marie, 60, cried uncontrollably when cops told her Wednesday night that he was arrested on charges of killing a little boy and stabbing his playmate in a Brooklyn elevator — and she told the detectives she feared he was out of his mind.

“I recommended that he be institutionalized,” Marie said, according to a source.

Asked by The Post about her warning, Marie said, “I don’t discuss work outside of my building. I’ve been told by my superiors directly not to discuss this issue. I can’t talk about anything outside of work.”

No formal recommendation was ever made for St. Hubert to be committed to a psychiatric facility, state Department of Public Safety officials said Thursday.

The accused stabber’s sister, Judith Perry, also said that system failed when she begged officials to treat him at the time of his release last month.

“We tried to get him to get help, we knew he had mental illness,” Perry said. “When he was released, they didn’t give him any kind of psychiatric evaluations or anything like that. They basically just sent him on his way.”

Perry claims she pleaded with social workers before and after her brother’s May 23 release from prison that he be given psychiatric care. “They told me it would take weeks for him to see a doctor,” she said.

Sources said Mayor Bill de Blasio was furious that St. Hubert was freed and has demanded an investigation.

Marie met with St. Hubert three times between his release and his arrest Wednesday in the knife attack that killed Prince Joshua “PJ” Avitto, 6, and wounded his pal Mikayla Capers, 7.

Marie first saw him at an East New York halfway house on the same day he was released into parole supervision from Clinton Correctional Facility.

He had just served five years in prison for choking his mother in her Jamaica, Queens, home in 2009 and for punching a female correction officer the following year.

Marie was so concerned at the first face-to-face meeting with him that she ordered a strict regimen of counseling and curfews, according to a police source.

Alcohol was forbidden, and he was banned from setting foot in a bar. He had to observe a curfew and could have no contact with anyone under 18, the source said.

Marie also ordered that he attend alcohol, drug and mental-health counseling sessions.

St. Hubert made his next two parole meetings, on May 27, then June 3, two days after the elevator stabbing, said state Public Safety spokeswoman Michelle Hook.

But he was a no-show on June 4 when summoned to return to the parole office, where cops — who had just gotten DNA results from the knife used to kill little PJ — were waiting to arrest him.

But St. Hubert skipped out on all of his counseling sessions — a clear red flag, the source said.

A spokeswoman for Public Safety, however, said officials were unaware of St. Hubert having missed any counseling.

Also, if he had been in violation of parole, the process of getting him into an institution would have taken weeks, the spokeswoman said.

St. Hubert was arraigned in Brooklyn Criminal Court late Thursday on charges of murder, attempted murder, assault, and criminal possession of a weapon.

He is slated to appear in Brooklyn Supreme Court on Friday so he can be assigned a homicide defense attorney.

The violent felon has a long criminal and psychiatric history.

6-year-old Prince Joshua Avitto was stabbed to death.

St. Hubert has nine prior arrests, including for possessing a knife and marijuana.

He had been found mentally unfit for trial for seven months before he pleaded guilty in June 2012 to choking his mother and punching the correction officer.

Court records show Queens prosecutors asked for just five years in prison for the assaults — both of which left their victims unconscious — even though he faced a maximum of 8¹/₃ to 25 years.

St. Hubert did his time at four upstate prisons. In his last year, he had only minor infractions for creating a disturbance, untidiness and disobeying orders.

But in March 2013, he spent three months in solitary for assaulting staff, his inmate disciplinary history shows.
