A Brooklyn mother accused of killing her emaciated 4-year-old daughter told a judge on Wednesday she’s “starving” for a speedy start to her murder trial.

Instead Carlotta Brett-Pierce, 30, got a dressing down from the judge after the prosecution revealed Brett-Pierce violated a court order by sending letters to her surviving children, one of whom is a witness in the case.

Brett-Pierce told Brooklyn Supreme Court Justice Patricia DiMango she sent the letters to her kids – ages 1 and 5 – to “tell them I love them.”

DiMango was unimpressed.

If you violate that order of protection from today forward I will deal with it more harshly than you can think,” DiMango said.

An indictment charges Brett-Pierce killed Marchella last September and lists the cause of death as “child abuse syndrome with acute drug poisoning, blunt impact injuries, malnutrition and dehydration.”

Brett-Pierce, whined that she hadn’t seen her other children in the five months she’s been held without bail.

“I’m starving for this trial to start,” she said, asking DiMango to impanel a jury immediately. “I did not hurt my baby. I did not kill my baby.”

DiMango demurred, citing essential pre-trial proceedings, but agreed to move the case along quickly.

Meanwhile, prosecutors said that a video cassette box and spatters on the wall tested positive for Marchella’s blood, but samples from a belt and buckle used to beat the child have not been analyzed yet.

Brett-Pierce, who pleaded not guilty, faces up to 25-years-to-life on charges of murder, manslaughter and assault, among others.

She will face additional charges if the letters contain any threats against the child-witness, prosecutors said.
