The Queens mom who pleaded guilty to manslaughter in the death of her 1-year-old daughter was sentenced to 4 to 12 years in prison on Thursday.

Tina Torabi, 30, was arrested Oct. 3 after cops found daughter Elaina unresponsive with bruises to her head, law enforcement sources told The Post at the time.

The tot’s twin brother, Keon, was also severely injured with broken ribs and a broken hip, cops said.

In May, Torabi copped to second-degree manslaughter and assault.

In Queens Supreme Court, Justice Richard Buchter handed down the sentence as a somber Torabi stood before him in khaki-colored jail clothes and long brown hair worn down.

The twins’ older sisters — Mila, 2, Nadia, 4, and Ariana, 5 — were at the home when the horrific incident happened and were taken into the custody by the Administration for Children’s Services after the incident.

Days after the killing, Torabi’s estranged husband Mohammad Torabi, 31, leaped to his death from the top of Midtown hotel.

A week after the slaying, ACS said they were eyeing Mohammad in Elaina’s murder, given that he fled and remained on the lam before his suicide. He also had a violent domestic history and was a convicted felon, ACS sources said at the time.

Police were also looking for Mohammad before his death, according to prosecutors.

Torabi’s defense lawyer, James Kousouros, told The Post, “the plea and sentence in this case was the result of intensive investigation by both sides. It was established that Ms. Torabi did not inflict injuries on her children but she took responsibility for her unfortunate failure to protect them.”

Kousouros said that Mohammad “was a vicious abuser … it was only the father who beat Ms. Torabi and was abusive of the children.”

“The judge made it very clear today that the evidence did not support that she inflicted the injuries. They were inflicted by her vicious husband.”

Kousouros said that Torabi is expected to serve just seven years because of an indeterminate sentence that allows inmates to be released on good behavior after serving 2/3 of their prison term.

Acting Queens District Attorney John Ryan said, “the baby twins lived in a house of horrors with their siblings … She [Tina Torabi] had an obligation to protect them from harm.”

“The defendant will have a long time to dwell on her failures that led to her own child’s death and to the other baby’s extreme suffering,” Ryan continued.
