A grand jury has returned a death penalty-eligible indictment against an Ohio mother charged with murdering her four-year-old daughter.

Tianna Robinson, 25, of Springfield Township is charged with one count of aggravated murder with a death penalty specification in the April 21, 2021 death of her daughter Nahla Miller. Robinson is also charged with two counts of murder, one count of felonious assault, and one count of endangering a child. According to Hamilton County Prosecuting Attorney Joseph T. Deters, Robinson strangled Miller “until her heart stopped” on April 13, 2021. Miller languished for eight days in the hospital; she died when she was removed from life support.

“Investigators believe Nahla had been abused for months,” Deters’ office said in a press release. “The Coroner’s Office has ruled Nahla’s death a homicide. The cause of death was determined to be strangulation and blunt force trauma, resulting in significant internal injuries.”

Robinson called 911 after allegedly committing the crime.

“My daughter’s not responding,” a voice believed to be Robinson said in the call.  “She just passed out.”

“Is her chest rising and falling like normal?” an operator asked.

“She was just fine, and then she passed out,” Robinson’s boyfriend, Rensley Washington, 25, responded on the call.

Washington said the girl woke up and passed out again. He later claimed Miller fell off a scooter.

Washington was arrested on a charge of obstructing justice. Police think he was lying about the whole thing.

The victim’s father, Nathaniel Miller, provided photos of his daughter to local television stations.

“I’m hurt,” said the father when his little girl died. “I would never have expected anything like this. And words can’t explain my pain.”

Robinson is accused of purposefully causing Miller’s death “with prior calculation and design” under Ohio Revised Code 2903.01(C). That language, when alleged against a victim under the age of 13, is enough for prosecutors to seek the death penalty under Ohio Revised Code 2929.04(A)(9), which reads:

The offender, in the commission of the offense, purposefully caused the death of another who was under thirteen years of age at the time of the commission of the offense, and either the offender was the principal offender in the commission of the offense or, if not the principal offender, committed the offense with prior calculation and design.

“I have never understood how anyone could hurt a little kid so badly, especially the child’s own mother,” Deters said. “Violence like this goes against every instinct we are born with as humans and as parents. These cases are exactly why I worked so hard in 1997 to help pass legislation making the purposeful murder of a child under the age of 13 a death penalty eligible offense.”

“This year has been especially difficult – with what seems like case after case of horrific acts perpetrated against children,” the prosecutor continued. “But rest assured we will not stop until justice has been served for Nahla Miller and her family.”
