A 19-year-old Highlands man was sentenced to 40 years in state prison Wednesday after pleading guilty to torturing his girlfriend's 8-year-old brother to death, closing out one half of a case that first drew Harris County sheriff's deputies to a Baytown hospital in February 2025. Nolan Stallings pleaded guilty in April to first-degree felony injury to a child causing serious bodily injury, admitting to abuse that prosecutors say unfolded over several days at a house in the unincorporated community of Highlands, east of Channelview.
A Guilty Plea Ends a Possible Life Sentence
District Judge Michele Oncken handed down the sentence following a hearing that lasted two and a half hours and included testimony from seven witnesses, according to the Houston Chronicle. Stallings had faced a possible sentence of up to life in prison under Section 22.04 of the Texas Penal Code, which sets a statutory range of 5 to 99 years or life for intentionally or knowingly causing serious bodily injury to a child under 15, as outlined by Sam Cammack III Defense Law. Prosecutors alleged Stallings struck the boy, identified in earlier reporting as Charles Walker, with a blunt object and his hand, and that he both failed to seek medical care for the child and failed to protect him.
The Chronicle's report, credited to reporter John Wayne Ferguson, notes that prosecutors had assembled crime scene photos, hospital records, cellphone evidence, an autopsy report and police statements as potential trial evidence before Stallings entered his plea. Stallings was arrested in March 2025 and later posted a $1 million bond after spending around 40 days in jail.
Injuries Compared to a High-Speed Crash
Harris County Sheriff's Office deputies responded to a hospital at 4401 Garth Road in Baytown on February 10, 2025, after the boy was transported there with various bodily injuries. His caretakers told hospital staff the injuries resulted from a fall, but deputies opened an investigation after hospital staff reported that the injuries were inconsistent with that account, according to KHOU 11. Medical evidence later showed the boy suffered severe skull fractures and internal trauma that treating physicians compared to the injuries of an unrestrained victim in a 70-to-80 mph car crash, as reported by Click2Houston.
The boy died after remaining in critical condition for several days at the hospital. Sheriff Ed Gonzalez confirmed the abuse occurred at a residence in the 100 block of Greendell Street in Highlands, where Stallings lived with his family, per KHOU 11's reporting. Following his death, the boy's family authorized organ donation, and Click2Houston reports that the donation saved the lives of five other children.
Girlfriend's Case Remains Active, With Competing Accounts
Stallings' girlfriend, Kara Walker, was 17 when she was arrested in August 2025, six months after Stallings' initial arrest, on first-degree felony charges of injury to a child causing serious bodily injury. The Harris County District Attorney's Office declined to comment Wednesday because her case remains active, the Chronicle notes. Prosecutors have written that both teens abused and tortured the boy over several days, but Walker has publicly disputed that account.
In a September jailhouse interview, Walker maintained her innocence, telling Click2Houston she found her brother motionless after hearing Stallings scream for her. She also said in that interview that Stallings had previously been physically abusive toward her before her brother's death, though she said she never reported those incidents to law enforcement. The dossier of evidence gathered by prosecutors and the competing accounts from the two defendants mean key questions about what happened inside the Greendell Street house remain contested as Walker's case moves forward.
Bail Decisions Diverged Sharply
After his March 2025 arrest, a Harris County judge set Stallings' bail at $1 million and denied his motion for a bond reduction, even though his attorneys argued for lower bail on the grounds that the incident occurred shortly before his 18th birthday, according to KHOU 11's earlier coverage. Walker's bail, by contrast, was set at $100,000 when she was arrested months later.
Because Stallings pleaded guilty to a first-degree felony classified as a “3G” violent offense under Texas Code of Criminal Procedure Article 42A.054, he will not be eligible for parole consideration until he has served at least half of his 40-year sentence, according to Texas Parole Representation. That classification also barred a judge from granting him standard probation.
Part of a Wider Pattern in Harris County
The case adds to a grim record for the region. Harris County recorded 28 confirmed child fatalities from abuse and neglect in 2022, more than any other Texas county, out of nearly 200 such deaths statewide that year, according to data reported by CBS News Texas. A separate multi-year investigation by Texas Public Radio found that among more than 1,200 children who died from abuse or neglect in Texas between 2018 and 2023, more than half came from families with prior reports on file with Child Protective Services.
Charles Walker's death, and the organ donations that followed it, stand as one thread of that broader pattern now working its way through the Harris County courts. While Stallings' sentence closes his portion of the case, prosecutors and Walker's defense remain at odds over her role, and her case is still pending resolution.
