A 38-year-old woman was arrested and charged with intentional child abuse resulting in death after police said her newborn daughter was found dead inside a portable toilet holding tank at a recreation area near Las Cruces. Investigators said an autopsy showed the baby was alive when she entered the tank and breathed and swallowed the blue sanitation liquid.
The case began as a medical call and quickly turned into a criminal investigation, with police racing late at night to locate a baby who was not at the hospital with the mother. Authorities said the infant’s death happened at Burn Lake, a remote site off Burn Lake Road, and that firefighters recovered the baby from the portable toilet tank. The defendant, Sonia Cristal Jimenez, was booked into the Doña Ana County Detention Center and initially held without bond, police said.
According to police, the investigation started at about 10:30 p.m. Sat., Feb. 7, when staff at Memorial Medical Center alerted officers that Jimenez had arrived and appeared to have recently given birth. Hospital staff told police the baby was not with her, and officers began asking how she had reached the hospital and where she had been earlier in the evening. Police said Jimenez’s boyfriend drove her to the hospital and spoke with investigators as they tried to determine whether an infant was in immediate danger.
Detectives said the boyfriend told them the pair had been at Burn Lake and that Jimenez had used the portable toilets at the site. Officers responded to the area, which police described as deserted at the time, and searched for a newborn. Police said they located the infant inside the holding tank of a portable toilet. Las Cruces firefighters recovered the baby from the tank, but the child was dead, police said. Authorities did not release the baby’s name.
Investigators said evidence indicated Jimenez gave birth at the recreation site, cut the umbilical cord and then placed the baby in the holding tank. Police described the infant as a baby girl and said they believed she drowned in the liquid inside the tank. The New Mexico Office of the Medical Investigator conducted an autopsy in Albuquerque, and police said the findings showed the baby had breathed and swallowed the blue chemical liquid used in portable restroom sanitation. Authorities said the chemical was found in the baby’s trachea, lungs and stomach, which they said supported the conclusion that she was alive when she entered the tank.
Police have not publicly described the full timeline between the birth and the hospital visit, and they have not released details about how long the baby may have been in the tank before being found. Investigators also have not described what Jimenez told medical staff or officers at the hospital, or whether she had sought prenatal care. Police did not provide information about any other children in the household or whether child welfare officials were involved in the response.
Authorities said they did not expect to charge the boyfriend. Police said they believed he was unaware Jimenez had given birth at Burn Lake. Investigators have not released his name, and police did not say whether he remained at the recreation site while Jimenez used the portable toilets or whether he had any reason to suspect a medical emergency had occurred there. Police said they continued to treat him as a witness as they built their case.
Jimenez was charged with one count of intentional child abuse resulting in death, a first-degree felony in New Mexico. Police said investigators obtained an arrest warrant, and Jimenez was taken into custody on Wed., Feb. 11. She was booked into the county jail, where she was initially held without bond, police said. Court records and jail logs were expected to show her first appearance and whether a judge would set conditions of release.
In New Mexico, child abuse resulting in death can carry severe penalties, and prosecutors typically rely on autopsy findings, witness statements and a careful reconstruction of events to prove what happened and when. Police have not released probable cause documents publicly in their statements, and they have not described whether the investigation included additional evidence such as video, phone location records or witness sightings at Burn Lake earlier that day. Authorities also did not say whether they recovered items from the portable toilet area, such as clothing, towels or other materials that could help establish what occurred in and around the stall.
Burn Lake is one of several recreation spots on the outskirts of Las Cruces, an area where night conditions can be quiet and dark and where portable toilets serve visitors. Police did not describe the level of traffic at the site on the night of the incident, or whether anyone else was present when the baby was born. Investigators said the location and the nature of portable toilet tanks can make searches difficult, and they credited the quick response after the hospital call with allowing firefighters and officers to locate the baby.
Officials emphasized the autopsy details because they speak to the baby’s condition at the time she entered the tank. Police said the infant’s breathing and swallowing of the sanitation liquid was a key finding that shaped the investigation. Authorities did not describe additional medical details, including whether the baby showed any other signs of trauma. Those details, if developed, are typically addressed in medical examiner reports and may later be presented in court.
The case also landed in a state where safe-haven options have been promoted after other high-profile incidents involving abandoned newborns. New Mexico’s Safe Haven law allows an infant 90 days old or younger to be surrendered at approved locations such as hospitals, fire stations, law enforcement agencies and designated baby boxes, according to state child welfare guidance and published summaries of the law. In Doña Ana County, officials have recently highlighted a Safe Haven Baby Box installed at a fire station in Anthony, a community south of Las Cruces, as part of a broader effort to provide anonymous surrender options for parents in crisis.
Supporters of safe-haven programs argue that easily accessible surrender locations can prevent tragedies, while law enforcement officials say criminal investigations remain necessary when an infant dies. In this case, police said they were focused on what happened in the portable toilet stall and the actions taken after the birth. The autopsy, they said, provided direct medical evidence that the baby was alive when she went into the tank, a point investigators said was central to the charge.
As investigators worked the case, the incident drew attention across southern New Mexico, including Las Cruces, where Memorial Medical Center serves as a regional hospital for a large stretch of the Mesilla Valley. Police did not describe the initial hospital report in detail, but they said staff recognized signs consistent with a recent birth and notified law enforcement. In cases involving suspected concealed pregnancies or deliveries outside medical settings, hospitals often alert police when a newborn is unaccounted for, prompting an emergency search.
The criminal process is expected to move next to early hearings, where a judge will address representation, bond and a preliminary assessment of probable cause. Prosecutors may seek detention based on the nature of the charge, while defense attorneys often challenge the evidence and request release conditions. Authorities have not said whether Jimenez has an attorney, and police did not provide a date for her first court appearance in their public statements.
For now, police said the investigation remains open as they complete interviews and review evidence connected to the trip to Burn Lake. Detectives are expected to continue documenting the timeline of the evening, including when the couple arrived, when Jimenez used the portable toilets and when she left the area for the hospital. Police also said they would rely on formal reports from the medical examiner as the case proceeds.
