Oxnard Mother Charged with Murdering Second Newborn in Decade-Old Cold Case

OXNARD, CA — A disturbing investigation into a recent newborn death at a homeless camp has led Ventura County detectives to uncover a second suspected killing from a decade ago. 

On March 10, 2026, the District Attorney’s Office filed an amended complaint against 30 year old Marisol Flores. 

She now faces two counts of murder and two counts of assault on a child causing death for separate incidents occurring in 2026 and 2015.

The current case began on February 8, 2026, when paramedics were called to a homeless encampment near West Vineyard Avenue in Oxnard. 

Upon arrival, emergency responders found a deceased newborn who showed clear signs of blunt force trauma. 

Detectives noted that witnesses saw Flores heavily pregnant only one day prior to the discovery. 

While she was initially booked on child endangerment charges, the discovery of the infant's body led prosecutors to upgrade the charge to first degree murder.

As investigators dug into the history of the 30 year old suspect, they revisited a dormant file from November 2015 involving the death of her 25 day old infant. 

At that time, authorities lacked the forensic evidence necessary to prove criminal intent and the case remained uncharged for over ten years. 

However, prosecutors now state that the evidence gathered during the 2026 homicide probe provided the missing links needed to implicate Flores in the earlier death as well.

The legal process is currently at a standstill as the court addresses the mental health of the defendant. 

During a late February court appearance, the defense attorney raised significant concerns regarding Flores' ability to understand the charges against her. 

Consequently, a judge has suspended all criminal proceedings until a court appointed psychologist can complete a full evaluation. 

A formal competency hearing is set for March 26, 2026, to determine if the double murder case will proceed to trial.
