A Tarrant County jury found 47-year-old Merria Sneed guilty of capital murder and injury to a child causing serious bodily injury for suffocating her 9-year-old niece, Melodi, with a pillow inside a Mansfield home in 2019, sentencing her to two life terms, one of them without the possibility of parole.
The verdict came seven years after the crime, according to a statement released by the Tarrant County DA. Assistant District Attorneys Charlie Boulware and Victoria Lydahl prosecuted the case, and Boulware told jurors during closing arguments that “Melodi's family has waited seven years, seven long years,” asking them for “a swift verdict for Melodi's family and for Melodi.”
According to the district attorney's account, Sneed was staying at her brother's new home on Eagle Drive in Mansfield on July 27, 2019, where family members had gathered to help unpack and celebrate the move. Late that night, after relatives throughout the house had gone to sleep, Sneed was in the game room where Melodi had fallen asleep on a couch, and she told her 13-year-old son to leave the room.
A Pillow, a Struggle, and a Confession
Once her son was down the hallway, Sneed picked up a blue and white pillow and pressed it over Melodi's face for several minutes, using her body weight to keep the child from moving, the DA's office said. “She fought. She screamed. She tried to stay alive,” Lydahl told jurors. “But she was only nine.”
The pillow muffled Melodi's attempts to scream. When the girl stopped struggling, Sneed lifted the pillow, wiped her niece's face, and removed the pillow from the house, according to prosecutors. Hours later, Melodi was found unresponsive, and police were called.
It was Sneed's own son who broke the case open. The boy told officers he saw his mother smother his cousin, and Sneed later admitted to suffocating Melodi, per the DA's statement. “It's extremely cruel and criminal, and there's only one person to blame,” Boulware said.
Timeline From 2019 Arrest to This Week's Verdict
Mansfield police and paramedics had responded at 12:38 p.m. on July 27, 2019, to a cardiac arrest call in the 4200 block of Eagle Drive, performing CPR on Melodi before rushing her to Methodist Mansfield Medical Center, where she was pronounced dead about an hour later, according to WFAA. An arrest warrant affidavit showed responding officers observed blood coming from Melodi's mouth during CPR, and that Sneed initially claimed she had only wiped foam from the girl's face before later confessing to pressing a pillow over her face for two to three minutes, the station reported.```Sneed attempted to clean Melodi's face with hydrogen peroxide after smothering her and then hid both the peroxide bottle and the pillow, according to a search warrant cited by CBSDFW. Sneed was arrested four days after the incident, on July 31, 2019, on a first-degree felony charge of injury to a child causing serious bodily injury, a charge prosecutors later upgraded to capital murder once they received formal autopsy results from the Tarrant County Medical Examiner, per the same WFAA report. Tarrant County Corrections Center booking records logged Sneed under a $250,000 bond following her 2019 arrest.
The Texas Department of Family and Protective Services removed another 3-year-old child from the Eagle Drive home following Melodi's death, WFAA reported at the time.
Why the Sentence Was Automatic
Under Texas Penal Code § 19.03(a)(8), intentionally causing the death of a child under 10 years old is automatically classified as capital murder, a capital felony, according to a legal explainer from Varghese Summersett. Because prosecutors in this case did not seek the death penalty, Texas Penal Code § 12.31 mandates an automatic sentence of life imprisonment without the possibility of parole for an adult convicted of capital murder, per the L&L Law Group.
Sneed's second conviction, for injury to a child causing serious bodily injury, is a first-degree felony under Texas Penal Code § 22.04 punishable by 5 to 99 years or life in prison, which explains how the jury arrived at a second life term alongside the capital murder count, Varghese Summersett's analysis notes.
The seven-year gap between the 2019 offense and this week's verdict reflects broader strain on Tarrant County's capital docket. A May 2026 report by the Texas Defender Service identified Tarrant County as a statewide outlier in capital prosecutions, accounting for nearly 25% of all Texas death penalty trials since 2020 despite housing only 7% of the state's residents, as Hoodline previously reported.
DA Investigator Matt Hardy and Victim Coordinator Elizabeth Garcia also worked on the case, according to the district attorney's office, which thanked the Mansfield Police Department for its investigative work and its commitment to community safety.
