A judge has sentenced Jacob Larosa to life in prison without the possibility of parole for the brutal 2015 killing of his elderly neighbor.

Larosa will also have to register as a Tier 3 sex offender for the rest of his life.

Prosecutors had asked the judge to impose a life sentence without the possibility of parole, but Larosa's attorneys had argued that his young age, along with psychological issues and a troubled childhood should be taken into consideration.

Larosa plead no contest in February to aggravated murder, attempted rape and theft in the death of 94-year-old Marie Belcastro.

 LaRosa was just 15 on March 31, 2015, when he broke into the Niles home of Marie Belcastro, attempted to rape her, and beat her to death with a heavy metal flashlight.

During the hearing, Judge Wyatt McKay said the court considered victim's statements, as well as testimony from police and the Trumbull County coroner. McKay also said he took into consideration a statement made by Larosa on his own behalf and Larosa's age at the time of the crime.

However, McKay also cited the brutality of the crime and the high likelihood of Larosa may commit future crimes.

"The defendant murdered a frail, 94-year-old woman who was known to be kind to him," McKay said, adding that Larosa has shown little to no remorse for the crime, even bragging to inmates about the murder.

 The death penalty was not an option because Larosa was just 15 when he committed the crime.

"There's no question that if he had been over 18 he would have gotten from any jury the death penalty. We couldn't give him the death penalty, Judge McKay thoughtfully, carefully and professionally examined all of the factors and gave the only sentence that he could make," said Assistant Prosecutor Chris Becker.

According to the defense, they already plan to appeal the judge's sentence.
