Candice McKinney had ended her relationship with Allen in early November 2015 “due to multiple incidences of domestic violence,” the district attorney’s office said. On Nov. 9, 2015, Erin McKinney, Candice’s sister, called 911 and said that she had been stabbed. She died while on the phone with a 911 operator.
Police found a “gruesome” scene in the Norcross apartment where Erin McKinney was fatally stabbed. Erin McKinney’s body was locked in a bedroom with her three children, all under the age of 7 at the time, the district attorney’s office said. Candice McKinney was “bleeding profusely” from multiple stab wounds and had collapsed in an outdoor stairwell, the district attorney’s office said.
Candice McKinney identified Allen as the person who stabbed her and her sister. After Allen was arrested, he told police that he believed Erin McKinney was “responsible” for his relationship issues with Candice McKinney, the district attorney’s office said.
At trial, Allen claimed he stabbed Erin McKinney in self-defense because she “attacked” him in the apartment. Allen had not previously told police that Erin McKinney attacked him, the district attorney’s office said.
Allen was sentenced to life in prison without parole plus 25 years.
