Robinson, 25, is charged with aggravated murder, aggravated arson and felonious assault in connection with May 11, 2023, incident on Arroyo Ridge Court in Fairfield Twp. If convicted he faces the death penalty.

Robbi Robinson Jr. will spend the rest of his life in prison without the possibility of parole for setting his father’s fiancée on fire in Fairfield Twp. in May 2023.

On Thursday, Butler County Common Pleas Judge Keith Spaeth followed the recommendation of the jury and sentenced the 25-year-old to life in prison in the capital murder case. He was also sentenced to an additional eight years for the felonious assault that happened minutes before the woman was set on fire

The jury considered four sentencing options for Robinson on the aggravated murder charge for killing Brenda Scott, 50. Those options were life in prison with the possibility of parole after 25 years, life in prison with the possibility of parole after 30 years, life in prison without the possibility of parole and death.

Following an unsworn statement by Robison, and testimony by family members and a psychologist, the jury recommended life without during the sentencing phase of the trial.

Robinson took the stand and asked the jury to spare his life, saying he is not “the worst of the worst.”

It was the job of the defense to present the jury with enough mitigating factors about Robinson to save his life. Their sentencing verdict indicates they believe the mitigating factors out weighed the aggravating factors of the crime.

Robinson’s mother, Renee Robinson, and 22-year-old sister, Zaria Robinson, testified during the sentence hearing about difficulties in their large, blended family, especially when the marriage of Renee and Robbi Sr. began to fall apart. Robinson took the stand to deliver an unsworn statement. Unsworn means he was not questioned by the defense or the prosecution.

“I am sorry that Brenda is dead. I am sorry that I am responsible for her death,” Robinson told the jury. “I made a bad decision, but I am not a bad person. I am not the worst of the worst.”

Robinson, who was described as a “sweet boy who wouldn’t hurt a fly” by his mother, but who struggled later in life around the time she separated from his father, said he felt abandoned by his family, noting no one showed up for court hearings or while he was in jail awaiting trial.

Zaria Robinson testified that in May 2023 her father gave her divorce papers to give to her mother. Zaria lived with her mother, and Robinson with his father.

At that time, Robinson said “I was not happy. I was not happy with a lot of things.”

During the statement to the jury, Robinson made an allegation about the victim and said his father “was not a good man to me.”

Renee Robinson said she did not realize her son had been impacted by altercations between herself and his father, as well as a stabbing incident between a half-brother and Robinson Sr.

Robinson also found his younger sister in the bathroom after she harmed herself.

She said he believes Robinson has mental health issues.

Robinson asked the jury to give him a life sentence with parole so he could one day be back in his sister’s life.

“I ask the jury to please spare my life,” he said. “I know for a fact I am a good human being at heart. I am sorry for what happened.”

Psychologist Dr. Jennifer O’Donnell, who met with Robinson several times for evaluation, testified Robinson has borderline personality disorder.

Assistant Prosecutor Katie Pridemore told the jury to rely on the evidence they heard during the trial to make the sentencing decision.

”You have already found the truth of what happened on May 11, 2025,” Pridemore told the jury. “I am confident the aggravating factors will outweigh the the mitigating factors.”

Scott was a nurse at UC West Chester with grown children. She met and fell in love with Robbi Robinson Sr. They were engaged and made plans to move in together.

“Little Rob,” as his family calls him, was not happy about the engagement.anger and took matters into his own hands,” Pridemore said.

Robinson also did not want to talk with or interact with Scott.

That opportunity came when Scott stayed at the Robinson house overnight and Robinson Sr., also a nurse, went to work the next morning.

Robinson put on a heavy “puffer” coat despite the 70-degree weather and carried the accelerant-filled bottles to the bedroom.

He burst into the room, knocked out Scott’s front teeth, then poured acetone and cigarette lighter fluid on the bed and her body, the assistant prosecutor told the jury.
