A babysitter was found guilty today of assaulting a 4-month-old boy who later succumbed to his injuries, the Los Angeles County District Attorney's Office announced.

Brittany Ann Ingrassi, 31, of Palmdale was found guilty of one count each of second-degree murder, assault on a child becoming comatose, child abuse and assault on a child causing death.

The jury also found true allegations that Ingrassi personally inflicted great bodily injury on the victim and he was under the age of five.

Sentencing is scheduled on June 2 in Department A17 of the Los Angeles County Superior Court, Antelope Valley Branch. The defendant faces 25 years to life in state prison.

Case MA068287 was prosecuted by Deputy District Attorneys Keri Knittel and Catherine Mariano.

On the morning of March 22, 2016, the baby, identified on the felony complaint as Aiden L., was left home under the care of Ingrassi, prosecutors said. When the victim's mother returned that evening, she was allegedly met by the defendant outside of the home and was made aware that the baby was not breathing, according to court testimony.

The mother then called 911 and the baby was transported to a local hospital with skull fractures and a traumatic brain injury. The infant died at the hospital on March 26, 2016. According to evidence presented at the trial, the defendant was unhappy being a babysitter and was under the influence of alcohol while caring for the victim.

The case was investigated by the Los Angeles County Sheriff's Department.
