Detectives say searches about concussion symptoms appeared on Tatiana Norman’s phone hours before she called 911 for her infant son.
LAKELAND, Fla. — Internet searches, video activity and medical findings became key pieces of evidence for Lakeland detectives investigating the death of 6-month-old Jeremiah Peters, whose mother gave several different explanations before acknowledging that she intentionally threw the infant into an uncushioned playpen, police said.
Tatiana Norman, 23, was arrested in late July and charged with aggravated child abuse after detectives compared her statements with an autopsy and the contents of her phone. Police say those records helped establish a timeline stretching from the morning of June 29 until a 911 call at 11:39 that night. Jeremiah was transported to Lakeland Regional Health Medical Center and pronounced dead shortly after midnight June 30. A medical examiner later classified the death as a homicide. Norman has not been convicted, and police said when announcing the arrest that prosecutors could still review whether other charges were appropriate.
The investigation did not begin with the account police ultimately made public. Norman initially told detectives that Jeremiah had fallen from a bed onto a tile floor while she was preparing a bottle, according to authorities. In another account, she said she had been in bed with Jeremiah and her 1-year-old child and suggested that she or the older child might have rolled onto the baby while sleeping. Those explanations became harder for investigators to accept after medical examiners evaluated Jeremiah’s injuries and police returned to Norman for additional questioning.
Detectives also focused on a mark on the baby’s leg. Norman first said it came from bathwater that was too hot, authorities said. She later attributed the mark to a possible reaction involving laundry detergent used by Jeremiah’s father. Police said she eventually told them that hot broth had spilled on the child’s leg. Investigators reported that the medical findings suggested a more significant heat-related injury than her original account indicated. Each shift added another question about whether the information provided immediately after Jeremiah’s death accurately described what had happened before the emergency call.
The autopsy became a turning point. Police said Norman was interviewed again after detectives were told that the injuries did not match the original bed-fall explanation. During that questioning, she described several events that had occurred throughout June 29. Unlike her earlier account, the later version stretched across much of the day and involved repeated impacts involving the infant. Police then compared that chronology with information stored on Norman’s phone, giving investigators a second source of timing evidence for periods when she said she was monitoring Jeremiah.
Norman said the first incident occurred around 9 a.m., when she accidentally dropped Jeremiah while reaching for a remote control, according to investigators. She said his head struck the floor. Police said she did not seek immediate medical care. Her phone instead showed searches for information about possible concussion symptoms. Investigators viewed those searches as significant because they suggested she was considering the possibility of a head injury while choosing to keep the baby at home. Authorities have said medical officials later believed immediate treatment might have prevented Jeremiah’s death.
A different event followed later in the morning, police said. Norman told detectives that her 1-year-old child climbed into or disturbed Jeremiah’s bassinet or rocker and caused it to tip, leading Jeremiah to fall face-first. Police did not describe the older child as a suspect. The incident was presented as part of the mother’s later account of what Jeremiah experienced during the day. It also added to the number of impacts investigators and medical officials had to consider when trying to understand the infant’s injuries.
Norman’s account then shifted from accidents to an intentional act. Around 1 p.m., police say, she became frustrated as the two children were crying. She described herself as overwhelmed or overstimulated while caring for them. Investigators said Norman admitted throwing or tossing Jeremiah from a standing position into a playpen that did not have padding underneath him. The baby struck the hard surface below. Police Chief Sammy Taylor Jr. said Jeremiah’s immediate reaction after that impact made investigators believe it may have been a particularly important point in the injury timeline.
What happened afterward is one reason the phone became central to the case. Norman told investigators Jeremiah became unusually sleepy and drank less formula. Detectives found searches seeking information about a baby feeling cold and whether a concussion in an infant was an emergency. Rather than showing only casual browsing, the phone data placed health-related questions alongside a period in which police say Jeremiah was displaying concerning symptoms. Investigators have not alleged that conducting an internet search itself was criminal; they cited the information to help establish what Norman may have known about the child’s condition and when she knew it.
The phone record also documented unrelated activity later in the day. Police said Norman watched TikTok videos, including cooking content, and accessed adult websites numerous times before emergency services were contacted. Authorities highlighted those records because they showed continued phone use after the medical searches. The evidence allowed detectives to compare a minute-by-minute digital trail with Norman’s description of monitoring her son. Prosecutors, however, would still have to prove the elements of any criminal charge in court, and the existence of online activity does not on its own establish criminal responsibility for Jeremiah’s death.
Police said there was another injury-producing event after the playpen incident. Norman eventually reported that Jeremiah fell from a bed and again struck his head. By the end of her later interview, detectives had an account involving several separate falls or impacts rather than the single accidental fall she initially described. Medical authorities determined that the overall pattern was consistent with the injuries found during the examination, according to police reports summarized by multiple news organizations. The full medical examiner’s findings, including a publicly specified cause of death, had not been released in the reporting reviewed for this article.
The timeline extended into the evening. At about 10 p.m., Jeremiah’s father sent Norman a message asking for a picture of the baby, police said. She did not provide one. The emergency call came at 11:39 p.m., when Norman reported that Jeremiah was unresponsive. First responders took the infant to the hospital, where he was pronounced dead at 12:32 a.m., according to local reporting. Taylor later said Jeremiah’s body temperature when he reached the hospital suggested to him that the child may have been dead for a period before the call was made.
That conclusion was distinct from the medical examiner’s formal classification. The examiner ruled the manner of death homicide, a medical determination that another person’s actions contributed to the death. Police had not publicly announced a final cause of death when they discussed Norman’s arrest. Investigators nevertheless said medical officials believed Jeremiah might have survived if he had received immediate care after he was injured. That assessment put the delay in seeking treatment alongside the alleged intentional throw as a major part of the case narrative presented by police.
Norman was booked on an aggravated child abuse charge, which Florida authorities described as a first-degree felony carrying a possible prison term of up to 30 years upon conviction. Police said the charge could be reconsidered or expanded after prosecutors reviewed the evidence surrounding Jeremiah’s death. A homicide manner-of-death ruling does not automatically determine which homicide offense, if any, should be filed; criminal charging decisions require prosecutors to evaluate the evidence and the legal elements of each potential offense.
Early coverage said Norman was being held without bond and had a court appearance scheduled for Sept. 1. Searches of publicly available reporting through Sept. 8 did not produce a reliable subsequent account confirming that prosecutors had upgraded the charge or describing a final resolution of that appearance. The case therefore remains one in which the police investigation has produced an aggravated child abuse allegation while the broader criminal consequences of Jeremiah’s homicide ruling remain subject to the court process. Norman is presumed innocent unless proven guilty.
