Second Murder Charge Added Against Oxnard Mother in Infant Death Case

Ventura County District Attorney Erik Nasarenko announced that  prosecutors have filed an amended complaint against Marisol Flores (DOB 09/11/95), of Oxnard,  adding charges related to a second alleged infant homicide. 

The amended complaint filed March 10, 2026, in Ventura County Superior Court, adds one count  of murder and one count of assault on a child causing death stemming from the alleged 2015  death of an infant. 

Flores was previously charged in connection with the alleged February 8, 2026, killing of her  newborn baby at a homeless encampment along West Vineyard Avenue in Oxnard. During the  investigation into the 2026 case, the Ventura County Sheriff’s Office reopened a previous  investigation into the November 2015 death of Flores’ 25-day-old baby. New evidence was  uncovered that led investigating deputies to believe Flores had killed that infant as well. 

Flores now faces two counts of murder and two counts of assault on a child causing death. Several  special allegations and aggravating factors have also been added, including use of a deadly  weapon, and that the victim was vulnerable. Prosecutors have also alleged in the amended  complaint the special circumstance that Flores committed more than one murder, which makes her  eligible for a sentence of life in prison without the possibility of parole if convicted. 

Senior Deputy District Attorney John Barrick of the Ventura County District Attorney’s Office Major  Crimes Homicide Unit is prosecuting the case. 

On February 27, 2026, Flores’ attorney declared doubt as to her competency to stand trial. All  criminal proceedings have been suspended, and a psychologist was appointed by the court to  evaluate her. She is scheduled for a competency hearing on March 26, 2026, at 9:00 a.m. in  courtroom 13.
