SALINAS, Calif. (KRON) -- The FBI and Monterey County Sheriff's Office held a news conference Thursday releasing heartbreaking details about how "Baby Angelita" was allegedly killed in Moss Landing before her 14-year-old mother was rescued in Mexico. The teenager, Diana, was pregnant from being se xually abused by her own father, 38-year-old Sergio Galvez Perez, authorities said. When Diana gave birth on the side of a road near a farm field on Aug. 1, she worried that her mother was going to "kill" her if she found out, Monterey County Sheriff's Detective Richard Geng told reporters. Diana had worked in farm fields since she was 13 years old, including the field that she gave birth next to. She routinely drove a beige Mercury sedan registered to her parents, investigators discovered. After giving birth without any medical attention, the teenager picked up her baby, placed her on the ground, and drove the car over Baby Angelita -- killing the newborn, Geng said. Sergio Galvez Perez is seen in a mugshot released by the Monterey County Sheriff's Office. Perez was in the San Francisco Bay Area when his daughter gave birth, and Diana later sent him text messages telling him what happened, Geng said. Hours after the homicide, the teen texted her father in Spanish, writing, "Dad! I couldn't hold it anymore and the baby came out. I hid it ... because my mom was going to see me with it, and she was going to kill me." Investigators said they did not find any evidence that Diana's mother and father knew about the teenager's intentions to allegedly kill Baby Angelita, authorities said. MCSO released this photo of the beige Mercury Milan sedan recorded near the homicide scene in Moss Landing, Calif. Diana's searches on the internet indicated that she was concerned about how to end the pregnancy, and what would happen when detectives found the baby, Geng said. Internet searches included questions about how to end a pregnancy, as well as, "how to turn off your iPhone location," according to Geng. On the morning of Aug. 1, when deputies found the newborn alone along Struve Road, they saw tire marks and "extensive" traumatic injuries, Geng said. MCSO investigators named the baby "Baby Angelita." When detectives arrived at the family's home in Salinas that afternoon, Diana "was hiding under a pile of clothes in a bedroom closet," Geng said. Detectives drove her to a hospital because they were concerned about her wellbeing. Before the girl was medically discharged from the hospital, her father showed up and took her away, authorities said. After Diana left the hospital, detectives were not able to find her for months. DNA results later confirmed that Perez was the biological father of the deceased newborn. The teen and her father vanished for two months. Officials issued a California Amber Alert on Sept. 6, and they considered her disappearance as a kidnapping. The FBI and Monterey County Sheriff's Office hold a news conference on Oct. 8, 2026. FBI Special Agent in Charge Scott Schelble described the case as "deeply troubling. What happened in this case is nothing short of horrific. It shocked us all. It became clear that a 14 year old victim endured unimaginable abuse." A journalist received a tip from a member of the public that revealed a possible location in Mexico. The manhunt for Perez expanded across the border. Schelble said, when a child is in danger, "borders do not diminish our determination." Mexican police authorities found and rescued the girl in Mexico last weekend, and her father was taken into custody. Schelble declined to say which state and city in Mexico they were found.

Sheriff Tina Nieto said her detectives spent countless hours working on the complex and "very difficult case" crossing international borders. Nieto said, "There's been a tremendous amount of public interest and criticism surrounding this case. I understand people have questions, the case generated strong emotions." Authorities described Diana as a sex abuse victim. Nieto said the newborn deserves justice. What that justice will look like remains unclear. Officials with the U.S. Department of Justice are currently seeking to extradite Perez from Mexico to face incest and child sex abuse charges filed by prosecutors in Monterey County. When asked if Diana will be transported back to California from Mexico, Schelble was uncertain. So far, Monterey County prosecutors have not filed murder charges against anyone connected to the baby's death, officials said. Diana's parents, Ofelia Garcia Ortega and Sergio Galvez Perez, are seen in mugshots released by the Monterey County Sheriff's Office. Diana's mother, 36-year-old Ofelia Garcia Ortega, was arrested in Salinas on Tuesday. Ortega is accused of using false documents to put her daughter to work in agricultural fields. "Ortega also allowed (the 14-year-old girl) to drive without a license and allowed her to completely remain out of school for many months,” prosecutors wrote. Prosecutors charged Ortega with permitting a child to suffer or be endangered, contributing to the delinquency of a minor, and displaying or possessing a forged identification card. ...read more read less
