The alleged demonstration became a key part of the capital murder case filed after the death of a 7-week-old Baytown infant.
BAYTOWN, Texas — Investigators say a Baytown father used an infant death investigation doll to show how his 7-week-old son bounced from a bed to the floor before the baby died of head trauma days later.
The walkthrough described in court records is one of the most detailed pieces of the capital murder case against Christopher Leon Jenkins. Police say the demonstration, Jenkins’ changing stories, a neighbor’s account and the autopsy findings helped prosecutors bring the charge nearly nine months after the July 2025 emergency.
According to the affidavit, police returned to Jenkins’ Baytown apartment during the investigation and gave him a SUIDI doll, a tool used in sudden unexpected infant death investigations. They told him to treat the doll as he would the baby. Jenkins allegedly paused and asked whether he could throw it. He then threw the doll onto the bed and described the infant moving across the mattress and falling to the floor. “He bounced so high,” Jenkins told investigators, according to the affidavit. Police said Jenkins pointed to the other side of the bed while explaining where the baby went, then demonstrated how he crawled over, picked the infant up and placed him back on the bed. The affidavit says he then shook the doll’s chest area while describing how he tried to see whether the baby was still alive.
The demonstration came after police said Jenkins had given several accounts of what happened inside the apartment. His first version, according to court records, was that the baby was asleep and he stepped outside to smoke a cigarette. Jenkins allegedly said he came back inside and found the child unconscious. Later, investigators said, Jenkins suggested he accidentally dropped the child while feeding him. In another account, he said the baby had been dropped while being taken from a bath. The doll demonstration shifted the account again, placing the child on a bed, then on the floor, before Jenkins allegedly picked him up and shook him. Police said the conflicting accounts raised questions about whether the injuries were accidental and when the child stopped breathing.
Investigators also cited Jenkins’ reported words about the infant’s crying. “There was too much crying in my mind,” he allegedly told police. “It just clicked.” Other reports on the affidavit say Jenkins said he became angry when the baby cried and that he lost his head. A witness told investigators she heard Jenkins yelling at the baby and telling him to “shut up” shortly before the crying stopped. The witness also described an earlier scene in which Jenkins pushed the baby in a stroller and lifted the infant with one arm after he began crying. Police did not present the witness as someone who saw the fatal blow. Instead, the affidavit uses the witness account to support the broader timeline and the allegation that crying preceded the emergency.
The medical emergency was reported July 25, 2025, at an apartment complex on East James Avenue. First responders found the infant lying on a mattress without a pulse, not breathing and with pink fluid coming from his mouth, according to the affidavit. The child was taken to a hospital and later transferred to Texas Children’s Hospital, where doctors treated him for brain bleeding and cardiac arrest. The baby died Aug. 1. Forensic officials later ruled the death a homicide caused by blunt force trauma to the head. Local reporting on the court records also described subdural hemorrhage and violent acceleration-deceleration forces, terms that prosecutors may use to connect the injuries to the alleged throwing and shaking described in Jenkins’ interview.
The baby’s mother told investigators she was in another apartment nearby with her mother when the emergency unfolded. Court records say she had left the infant with Jenkins, and about 20 minutes later Jenkins came over and said something was wrong. A 911 call was made. Police wrote that the baby was alone with Jenkins during the time when the fatal injuries were believed to have occurred. Jenkins allegedly estimated that about 15 minutes passed between the moment he picked the child up from the floor, placed him on the bed and called 911. That estimate, if prosecutors use it in court, could become important because it describes a delay after the alleged impact and shaking but before help was requested.
Jenkins was charged with capital murder in late April. The charge is tied to the age of the victim under Texas law, because the case involves a child younger than 10. He was arrested and booked into the Harris County Jail. Court reporting said a judge found probable cause at an early hearing and scheduled further proceedings on his custody status. Prosecutors had not publicly said whether they would seek the death penalty. The distinction matters because a capital murder charge does not automatically mean prosecutors will pursue that punishment. It does mean the case will follow the serious felony track in Harris County, with medical experts, police witnesses and family members likely to be central to the prosecution’s presentation.
The defense has begun with a limited public response. Attorney Kathryn Kahle told Oxygen that Jenkins had not yet entered a plea and said, “We look forward to vigorously defending Mr. Jenkins in court.” Defense lawyers may challenge how the statements were taken, whether the walkthrough accurately reflected what happened, and whether the medical findings prove the prosecution’s theory beyond a reasonable doubt. They may also examine the timeline surrounding the 911 call and the child’s hospital treatment. None of those arguments has been fully presented in a public trial. At this stage, the affidavit provides the state’s version of events, not a finding of guilt.
The use of a doll in the investigation shows how police tried to move beyond verbal accounts. A physical demonstration can help investigators understand distance, force, sequence and whether a person’s description matches injuries. It can also become contested evidence if a case reaches trial. Jurors could be asked to decide how much weight to give Jenkins’ reported actions with the doll and whether they show intent, recklessness, panic after an injury or some other state of mind. The affidavit says Jenkins used the doll to show both the alleged throw and the later shaking, but it does not publicly answer every question about force or exact positioning.
The apartment itself remains central to the case. The child’s mother and grandmother were close enough that Jenkins could reach them quickly, yet police say the baby was alone with him when the injuries occurred. The neighbor’s account placed shouting and crying near the same period. Medics arrived to a scene that records describe in stark medical terms, with the child pulseless on a mattress. Hospital staff then treated injuries that later became the foundation for the homicide ruling. The prosecution’s burden will be to turn that sequence into proof of capital murder, while the defense will seek to raise doubt about the state’s interpretation of events.
Christopher Jenkins remains accused, not convicted, as the Harris County case continues. Future hearings are expected to address custody, evidence, statements and trial scheduling, with the doll demonstration and the autopsy findings likely to remain at the center of the dispute.
