A Baton Rouge judge on Monday refused to reconsider the 35-year prison term he gave Brittany Monk for her role in the savage 2015 beating, strangling and stabbing death of her convicted molester in his Zachary trailer.

The 20-year-old Walker woman's attorneys had filed a motion earlier this month, arguing that her manslaughter sentence, which was five years shy of the maximum possible penalty for that crime, was excessive.

But state District Judge Tony Marabella denied the motion Thursday without issuing written reasons. Monk's attorneys did not immediately respond Monday to a request for comment.

Monk was 17 and seven months pregnant when she and her then-fiance, Jace Crehan, broke into Robert Noce Jr.'s mobile home and killed him, less than two weeks after the 47-year-old Noce pleaded "no contest" to sexually abusing Monk as a child. Noce was a former boyfriend of Monk's mother.

Monk's attorneys, Lindsay Blouin and Joshua Newville, argued in their motion for sentence reconsideration that Monk was an immature teen who made a "terrible, catastrophic mistake in judgment."

"Sentencing her to 35 years as if she were an adult in full control of reason, risk-management, and impulse is wrong," they wrote in the motion. "It goes against the United States Supreme Court's recognition that children are different and should be treated so in the eyes of the law."

Blouin and Newville asked the judge to either resentence Monk to a penalty "proportionate with her young age" or defer ruling on their motion "until such time that (he) feels she has demonstrated positive custodial adjustment." The lawyers said Monk has demonstrated positive maturation over the last two years while imprisoned.

Monk pleaded guilty to a manslaughter charge in June, testified in December at Crehan's second-degree murder trial and was sentenced last month to 35 years behind bars. She admitted punching Noce 10 to 15 times while Crehan held him down, and also said she retrieved the knife from Noce's kitchen that Crehan used to stab him numerous times.

Crehan, 24, also of Walker, was convicted as charged and sentenced to a mandatory term of life in prison.

Monk's body was found stuffed inside a 55-gallon plastic container in his kitchen July 4, 2015.

In sentencing Crehan and Monk on Jan. 19, Marabella called the slaying a "diabolical" act and "vigilante" justice.

The judge pointed out that Monk had no reason to fear Noce because he had absolutely no contact with her for the three years leading up to his June 2015 no contest plea. He was put on probation.

"Ms. Monk may not have seen her abuser for 3 years, but she still lived each and every day with the effects of the sexual trauma inflicted on her for the better part of a decade," Monk's attorneys argued in their motion.

In addition to Monk's youth and immaturity at the time of the crime, Blouin and Newville also pointed the finger at Crehan and his "negative influences."

In addition to living with Crehan — the father of her child — at the time of the killing, Monk's lawyers said he had "unwittingly exposed her and her baby to a sexually transmitted disease due to his infidelity."

"Her only alternative would have been to return to the equally unstable, substance abusing mother who had originally left her as a 4-year-old child with her abuser, Robert Noce," her lawyers said.

Blouin and Newville argued further that Monk's immaturity and devotion to Crehan "meant that she did not question the viability of his immature, catastrophic plan to scare Robert Noce into staying away from them that went terribly wrong."

Monk's attorneys contend she was a "young girl trapped in circumstances that the Supreme Court has acknowledged should lead to forgiveness in part of that child's actions."
