WARREN — “There’s nothing like the loss of a child,” Linda Monday said in court Tuesday during the sentencing hearing of the man convicted of killing her grandson.

“I’m here asking for justice for Kardell,” she said, referring to Kardell Lowery, who was shot to death in a Warren apartment last summer.

Her plea was answered as Tyree Brown, 29, was sentenced to 36 years to life in prison for the execution-style killing of Lowery at the Hampshire House complex July 10. Brown’s first chance at parole will come after he serves 36 years, plus an additional six years for two firearm specifications.

A Trumbull County jury found Brown guilty last week on two counts of aggravated murder, two counts of aggravated burglary, and one count of having weapons under disability, along with firearm specifications.

Trumbull County Common Pleas Judge Cynthia Westcott Rice, in delivering the sentence, described Brown’s actions as “more serious” because of the premeditated nature of the crime.

“This was a calculated act of violence carried out with prior design,” Rice said.

Brown and his co-defendant, Michael Williamson, were accused of targeting Lowery in retaliation for a prior altercation. Williamson pleaded guilty earlier this month to voluntary manslaughter and was sentenced to 20 to 25 years in prison.

The same offer was extended to Brown but was declined, leading to a trial.

During the three-day trial, prosecutors painted a grim picture of the crime. Trumbull County Assistant Prosecutor Gabriel Wildman called the shooting a “cold-blooded execution.” Evidence presented over three days showed that Lowery had previously beaten Williamson after Williamson assaulted Lowery’s girlfriend, Amari Williamson. Testimony from Amari and Lowery’s 9-year-old son detailed the events leading up to the murder.

Forensic Pathologist Dr. George Sterbenz, who performed the autopsy, testified that Lowery suffered two gunshot wounds. The fatal shot was a “tight contact” wound to the left side of his head, which caused an explosive injury that tore apart his ear, fractured his skull, and severed his brainstem, resulting in immediate death. A second gunshot to the lower back caused internal bleeding but was not fatal, Sterbenz said.

Forensic scientist Stacy Viola testified that DNA from both Brown and Lowery was found on pieces of a blue latex glove recovered near the scene. Viola said the statistical likelihood of the DNA match belonging to someone other than Brown was one in 200 million.

In her victim impact statement, Monday described her grandson as “one of the loves of my life” and called the killing a “premeditated execution brought on by hate, fear, envy, spite, and cowardice.”
