In a stunning new development that has sent shockwaves through the ongoing investigation into the tragic death of a young mother in Los Angeles, a mysterious woman has walked into a police station and identified herself as the secret mistress of Ruben Fregoso, the 40-year-old suspect wanted in connection with the murder of his girlfriend and the abduction of their five-year-old daughter.

According to details emerging from the case, the unidentified woman voluntarily appeared at the station and handed over a black smartphone, claiming it contained critical communications and evidence related to her alleged romantic involvement with Fregoso. Authorities are now examining the device for potential clues that could shed light on the suspect’s motives, movements, and state of mind in the days leading up to the horrific incident.

The backdrop of this revelation is the deeply disturbing case that began on May 24, 2026, when police responded to a welfare check at a home in Los Angeles’ West Adams area. There, officers discovered the body of 36-year-old Marisol Garcia Palacios, who had suffered a violent death. Fregoso, identified as her partner and the father of their young daughter Daleyza (also referred to as Daleza), quickly became the primary person of interest.

Investigators believe Fregoso fled the scene with the five-year-old girl in a white 2019 Land Rover Discovery. Surveillance footage later captured the pair at a parking garage in San Ysidro near the U.S.-Mexico border, suggesting he may have crossed into Mexico in an attempt to evade capture. An Amber Alert was swiftly issued, sparking a multi-agency and cross-border search effort. Fregoso faces charges including murder and child abuse, with prosecutors warning he could spend the rest of his life behind bars if convicted.

The emergence of a self-proclaimed mistress adds a layer of complexity and potential motive to the already heartbreaking saga. Sources close to the investigation indicate that the black phone could hold text messages, photos, or call logs that reveal a hidden double life. Did Fregoso’s alleged affair contribute to escalating tensions in the household? Was there jealousy, financial strain, or threats involved? These are the pressing questions detectives are now pursuing.

Neighbors who knew the family described Marisol as a devoted mother who doted on little Daleyza. A growing memorial of flowers, candles, and heartfelt notes has formed outside the family home, reflecting the community’s grief and outrage over the loss of a young life cut short. Many are pleading for the safe return of the innocent child, who remains missing alongside her father.

As authorities continue to comb through digital evidence and international leads, this latest twist raises hopes that the black phone might provide the breakthrough needed to locate Fregoso and reunite Daleyza with her extended family. The case serves as a grim reminder of how domestic conflicts can spiral into unimaginable tragedy, leaving behind shattered lives and unanswered questions.

Police are urging anyone with information about Fregoso’s whereabouts or the child’s location to contact authorities immediately. The investigation remains active, and more revelations could surface in the coming days as forensic analysis of the surrendered device progresses.
