A 42-year-old Salt Lake City man is being held without bail in the Salt Lake County Jail after prosecutors charged him with recklessly causing the death of his 7-month-old daughter, who was found unresponsive on a mattress in an unfinished basement littered with drugs, garbage, and bottles of urine. Neal English Colby was booked into custody on August 13, nearly 19 months after Murray police responded to a report of a baby in full cardiac arrest at the family's residence.
Colby is charged with child abuse homicide and child endangerment resulting in death, both first-degree felonies under Utah law, according to charging documents cited by KSL News. Prosecutors have asked that Colby not be allowed to post bail pending trial. Court filings say Colby and the infant's mother were separated but living in the same residence, with the mother staying upstairs while Colby lived in the basement.
The baby, Celia Aurora Colby, died on January 17, 2025, while she was being transported to the hospital, according to an obituary published by Larkin Mortuary. She had been born on June 18, 2024, and was later buried in the section of Larkin Sunset Gardens in Sandy known as “Babyland” following a private viewing.
A Middle-of-the-Night Handoff Turns Deadly
Charging documents state that Celia's mother brought the baby down to Colby at about 2:30 a.m. so he could watch her. Celia's mother had told investigators that she and her young son had been sick with the flu and that Celia was showing the same symptoms; she also said she had an appointment to see a pediatrician later that day, per the charges described by the outlet.
According to those charges, Colby left the residence at 3:21 a.m. that morning and left Celia alone without supervision for 43 minutes. When Celia's mother later went downstairs, she found the baby lying face up on Colby's bed and reported that red fluid was coming from her, according to charging documents. She began performing CPR, gave Celia children's Tylenol, and called 911.
Body Camera and Phone Data Raise Questions
Responding officers' body-camera footage showed that Colby appeared to display no remorse and was vaping when officers were not looking at him, the charges state. Colby told investigators he did not know what happened and did not call 911 himself. Investigators also noted that Colby's phone remained in an area Murray police consider known for drug activity, per the charging documents.
Detectives who searched the residence located bottles of urine near the bed, drugs and drug paraphernalia, and reddish fluid on a dark blanket on the downstairs mattress. Court documents cited by Law & Crime further describe THC wax found stored near baby food in the basement, alongside the illicit substances and paraphernalia scattered through the room.
Medical Examiner Cites Abrasions, But Manner of Death Unresolved
The Utah State Medical Examiner's Office found abrasions along Celia's nasal alae, right cheek and chin, according to the charges, and reported that the injuries could indicate airway obstruction caused by external force. Despite that finding, Celia's manner of death was ultimately certified as could not be determined — the medical examiner did not reach a conclusive ruling.
A child abuse pediatrician who reviewed the case reported that a caregiver pinching a child's nose shut can cause the kind of injury pattern observed on Celia, and said the abrasions to her nostrils were highly concerning. The pediatrician also stated that it could not be ruled out that an adult manually obstructed Celia's airway, while cautioning that an asphyxia death may not always be identifiable at autopsy, according to the charges.
Under Utah Administrative Code R512-205-4, the state's Child and Family Services division is required to accept allegations of physical abuse for investigation whenever a case involves obstructed breathing or pressure applied to a child's nose or mouth, as outlined by the Legal Information Institute. Separately, Utah Code § 62A-4a-405 requires that any suspected abuse or neglect death be reported immediately to the local medical examiner, district attorney, and state child welfare officials, per the Child Welfare Information Gateway.
Pediatrician Flagged Hazardous Living Conditions
Beyond the physical injuries, the child abuse pediatrician identified human waste, animal waste, and illicit drugs throughout the environment where Celia was found — described in charging documents as an unfinished basement that was very dirty, with garbage and property scattered around the room. The pediatrician determined that the conditions were harmful and potentially dangerous, and reported that the environment was unhealthy and dangerous for a developing child even if she had been supervised. The pediatrician also said the environment could have contributed to Celia's death.
Under Utah Code § 76-5-112.5, child endangerment through exposure to controlled substances or paraphernalia is generally a third-degree felony but escalates to a first-degree felony when that exposure results in a child's death, according to Justia Law. A first-degree felony conviction in Utah carries a statutory sentencing range of five years to life in prison, along with fines up to $10,000 under Utah Code § 76-3-203, according to attorney Edward D. Flint. Utah's indeterminate sentencing structure means the state Board of Pardons would ultimately set any actual release date within those statutory limits.
Part of a Broader Pattern of Utah Infant Fatality Cases
Preventable injury deaths accounted for 27.5% of all child fatalities among Utah youth ages 0 to 17 between 2013 and 2022 — 1,077 out of 4,286 deaths — according to the Utah Department of Health and Human Services. The state also maintains a statutory Fatality Review Committee under Utah Code § 26B-1-506 that convenes law enforcement, medical experts and prosecutors to examine child deaths involving families with recent contact with state social services.
Colby's case echoes another prosecution Hoodline covered involving a neglected Cache County toddler, in which a couple was charged with aggravated murder and child abuse after their 18-month-old daughter died in an unsanitary room from severe neglect in December 2025. As in that case, Utah prosecutors in the Colby matter have paired a homicide-level charge with an environmental endangerment charge, allowing them to pursue both a theory of physical harm and one centered on hazardous living conditions.
The nearly 19-month gap between Celia's death and her father's arrest reflects the extended, multi-agency nature of the investigation, which involved Murray police, the medical examiner's office and a child abuse pediatrician before formal charges were filed in Utah's 3rd District Court. All allegations against Colby remain unproven in court pending trial.
