Prosecutors, who had asked for a term of at least 25 years, said they were satisfied with the sentence that Judge Pate handed down.
“At every turn, Mr. Darby refused to take any responsibility for what he did, and he would never admit that he did anything wrong,” Timothy R. Gann, the chief deputy district attorney of Madison County, said in an interview on Friday.
“There was no remorse from him about the killing,” Mr. Gann said. “There was no acknowledgment from him about the gravity of what he did. That was one of the most disturbing things about the case.”
Officers called to Mr. Parker’s house found him “suicidal” and holding a gun, the police said in a statement in August 2018. After Mr. Parker disregarded several orders to drop his weapon, Mr. Darby fatally shot him, the police said.
According to a lawsuit filed by Mr. Parker’s family, Mr. Darby was the third officer to arrive at Mr. Parker’s house that day.
Officer Pegues had entered with her gun pointed down and found Mr. Parker sitting on a couch with a gun to his head, according to the lawsuit. She had been talking to him when Mr. Darby arrived about five minutes later, according to the lawsuit.
Mr. Darby began screaming at Officer Pegues while he was still in the front yard, according to the lawsuit, telling her to point her gun at Mr. Parker because “he can shoot you!” Mr. Darby then repeatedly yelled at Mr. Parker to put his gun down before firing a single shot that killed Mr. Parker, the lawsuit states.
