Teen Admits to Murdering Grandmother, Pleads Guilty but Mentally Ill
A 19-year-old man from Kentucky has confessed in court to the brutal murder of his grandmother, an act described as unprovoked. Wyatt Testerman entered a guilty but mentally ill plea on Tuesday.
This plea allows Testerman to receive mental health treatment while serving his time within the state prison system. Notably, he did this without prosecutors’ agreement. Rob Sanders, the Kenton County Commonwealth’s Attorney, stated that his office aims to pursue a life sentence.
According to prosecutors, Testerman recorded the brutal attack on 74-year-old Cheri Oliver at her residence in October 2024. The footage allegedly shows him pushing her to the ground before he starts striking her. There’s a disturbing moment captured where he pauses to check her pulse and exclaims, “I’m sorry. [expletive] Is she still breathing?”
Testerman reportedly hit Oliver over 40 times with a metal cup and other items, and stomped on her approximately 12 times. Authorities found Oliver unconscious and surrounded by blood; she later succumbed to blunt force trauma.
The situation escalated when Testerman’s mother attempted to intervene during the attack. Witnesses conveyed that Testerman had previously made alarming accusations against Oliver, branding her a “suicide” and a “terrorist,” and warned her of dire consequences if she didn’t comply with his demands.
Testerman later revealed in court that he had been struggling with substance abuse, specifically mentioning the use of acid, which he claimed contributed to his actions that day. “That day, I attacked my grandmother for no reason and beat her repeatedly to death,” he stated.
Initially, an insanity defense was anticipated as the trial was set to commence on May 12, but subsequent assessments from defense experts indicated Testerman was suffering from antisocial personality disorder.
During the proceedings, he mentioned experiencing hallucinations but also recognized the gravity of the trial, understanding the process as it unfolded. Ultimately, he received a sentence of 20 years to life, with formal sentencing scheduled for July 7.
