A Georgia court has sentenced a 37-year-old woman to life imprisonment for the murder of Melvin Cooksey, the man who had employed her as a caregiver following his stroke.
Danetta Knoblauch was found guilty of felony murder in November for the 2023 death of 57-year-old Cooksey, according to a statement from the Alcovy Judicial Circuit District Attorney’s Office. On Wednesday, the court handed down a life sentence without the possibility of parole, in addition to 30 more years.
The case began on February 23, 2023, when Newton County deputies responded to a fire at Cooksey’s residence on Mote Road. Investigators concluded that the blaze was deliberately ignited, with propane tanks strategically placed throughout the house. Despite the extensive search efforts that followed, Cooksey remained missing after the incident.
A breakthrough came in May 2023 when hikers in Fannin County, roughly 130 miles from Cooksey’s home, discovered a skull and other skeletal remains. A body found with a pacemaker was later confirmed to be Cooksey’s through the device’s serial number. Investigators linked Knoblauch to the crime using witness accounts, social media evidence, and data from license plate readers.
Knoblauch’s criminal past also came to light during the investigation. She was already wanted in Kansas for assaulting a man with a sledgehammer and screwdriver. Law enforcement eventually located her in East Baton Rouge, Louisiana, where she had barricaded herself inside a home with her child. After a prolonged standoff, she was apprehended and reportedly provided “incriminating information.”
In July 2023, Knoblauch was extradited to Georgia and subsequently charged with murder and additional offenses in August.
According to a courtroom report from the Atlanta Journal-Constitution, Cooksey suffered a stroke which caused heart problems and forced him into a wheelchair. He put out an online advertisement for a caregiver. The defendant responded to the ad and moved from Kansas to Georgia to care for him. But within days, she beat him to death with a sledgehammer before transporting his body to the mountains more than 100 miles away.
In addition to murder, jurors also convicted Knoblauch of aggravated assault, first-degree arson and concealing the death of another after the weeklong trial.
“Because of the tireless work of the prosecution team and the lead investigators, the person responsible for this senseless and heinous crime has been convicted,” District Attorney Randy McGinley said in a statement. “This was a complicated case that required expertise in so many areas and a dedication to finding the truth.”
Cooksey’s family members followed the case every step of the way and were pleased to receive justice.
“He had [a] good spirit,” his sister Brenda Hardy told the Journal-Constitution. “He didn’t deserve what happened to him at all.”
As for Knoblauch, she never admitted to the killing.
“I am innocent,” she said before deputies led her away in handcuffs.
