VENTURA, CA — Prosecutors in California have filed additional charges against a woman accused of killing her newborn earlier this year, alleging she was also responsible for the death of another infant more than a decade ago.
The Ventura County District Attorney’s Office announced that an amended complaint was filed March 10 against 30-year-old Marisol Flores, adding one count of murder and one count of assault on a child causing death related to the alleged November 2015 death of a 25-day-old baby, according to District Attorney Erik Nasarenko.
Flores had already been charged in connection with the alleged Feb. 8, 2026 killing of her newborn at a homeless encampment along West Vineyard Avenue in Oxnard, the district attorney’s office said in a news release.
According to prosecutors, investigators reopened the 2015 case while examining the circumstances surrounding the newborn’s death earlier this year. The Ventura County Sheriff’s Office revisited the earlier investigation after Flores’ February arrest, officials said.
“New evidence was uncovered that led investigating deputies to believe Flores had killed that infant as well,” Nasarenko said in the release.
Flores now faces two counts of murder and two counts of assault on a child causing death, according to court records and the Ventura County District Attorney’s Office.
The February case began when first responders were called to a homeless encampment in the 2400 block of East Vineyard Avenue after a concerned passerby dialed 911, according to the Oxnard Police Department and reporting by the Ventura County Star. Emergency personnel pronounced the infant dead at the scene and noted a suspicious injury, police said.
Authorities previously said the infant — a boy who was one day old — showed signs of blunt force trauma when officers arrived.
“As they went to render aid to the infant, they quickly determined the infant showed no signs of life and the infant was pronounced deceased shortly thereafter,” police previously said. “The mother of the infant, Marisol Flores, a 30-year-old, Oxnard resident remained at the scene. She was transported to a local hospital for medical aid. Fire and EMS personnel took note of a suspicious injury to the infant and shared their findings with the police personnel on scene.”
Witnesses had reported seeing Flores visibly pregnant the day before the baby was discovered, but when they saw her again the next day she was no longer pregnant and the infant was not with her, Nasarenko previously said, according to KRCG.
The Ventura County Medical Examiner’s Office later determined the newborn died from a sharp force injury to the head and ruled the manner of death a homicide, according to the Ventura County Star.
Flores was taken to a hospital after the Feb. 8 incident and was arrested the following day, according to police.
After her arrest, investigators reopened the 2015 death of Flores’ 25-day-old baby. Authorities said newly uncovered evidence led deputies to conclude she allegedly killed that infant as well.
Prosecutors have also added several special allegations in the amended complaint, including use of a deadly weapon, that the victims were particularly vulnerable and that Flores committed more than one murder, according to the district attorney’s office. If convicted and the allegations are proven, she could face life in prison without the possibility of parole.
Senior Deputy District Attorney John Barrick of the Ventura County District Attorney’s Office Major Crimes Homicide Unit is prosecuting the case.
Criminal proceedings have been suspended after Flores’ attorney declared doubt about her competency to stand trial. According to prosecutors and court records, a psychologist has been appointed to evaluate whether she can understand the legal proceedings and assist in her defense.
Flores has not yet entered a plea. She remains in custody at Todd Road Jail in Santa Paula with bail set at $500,000.
A competency hearing is scheduled for March 26 at 9 a.m. in Ventura County Superior Court.
Presumption of Innocence: A presumption of innocence means that any defendant in a criminal trial is presumed to be innocent until they have been proven guilty beyond a reasonable doubt in a court of law. The defendant in this case is only accused of the charges set forth in the criminal complaint. They are innocent until proven guilty.
