A newborn found dead beside a Monterey County road in August suffered crushing injuries after being run over by a car driven by her 14-year-old mother, investigators said Thursday. Detectives believe the infant, whom authorities call Baby Angelita, was moved several feet from where she was born to a spot beneath the vehicle, Monterey County Sheriff’s Office Detective Richard Geng said at a news conference in Salinas. No one has been charged with homicide in connection with the baby’s death, he said. Deputies were called to Struve Road, north of Moss Landing, at about 8:30 a.m. Aug. 1. They found the newborn on a dirt shoulder beside an agricultural field. She was pronounced dead at 8:46 a.m. Witness statements, video, automated license plate reader records and evidence from a beige Mercury sedan helped detectives identify the vehicle as registered to the teenager’s father and mother, Geng said. Witnesses reported seeing the teenager get into the driver’s seat before the car left. Investigators said phone records, video and work timecards also indicated she had driven herself and her mother to work in the fields that morning. About four hours after the baby died, the teenager sent her father a message saying she had given birth and hidden the infant because she feared her mother’s reaction, according to Geng. He read a translated portion at the news conference: “A while ago, I couldn’t hold it anymore, and the baby came out. I hid it somewhere because my mom was going to see me with it, and she was going to kill me.” Investigators said the teenager’s phone also contained months of searches related to concealing or ending a pregnancy. On the day the baby was found, she searched what would happen if police found a newborn belonging to a minor, then how to turn off her phone’s location tracking, Geng said. The investigation has also uncovered allegations of sexual abuse. DNA results received Aug. 19 identified the teenager’s father, 38-year-old Sergio Galvez Perez, as the biological father of both the teenager and the baby, Geng said. Perez faces U.S. felony charges alleging incest, child abuse and a lewd act on a child younger than 14. He was arrested in Mexico on local drug-possession charges, and U.S. authorities are seeking his extradition, FBI special agent in charge Scott Schelble said. The teenager remains in Mexico under the care of Mexican child-protection authorities. Investigators said Perez removed her from a hospital before she was medically discharged after she was found at the family’s Salinas home on Aug. 3. The pair then went missing, triggering an Amber Alert and a search. Officials did not announce plans to seek the teenager’s extradition. The teenager’s mother, 36-year-old Ofelia Garcia Ortega, was arrested Tuesday on charges involving forged identification, child endangerment and contributing to the delinquency of a minor. Investigators allege she used falsified documents to put her daughter to work at age 13, allowed her to drive without a license and kept her out of school. Sheriff Tina Nieto defended the investigation Thursday after criticism of an earlier decision to describe the teenager as a murder suspect. The Monterey County District Attorney’s Office has said no charges were filed against her. “It’s important to remember that the case involves a 14-year-old child who is also the victim of very serious crimes,” Nieto said. “Her safety, privacy, and well-being have remained a priority, and will continue to remain a priority.”
