He was already serving 116 years behind bars. Here's why a judge gave him another life sentence.

He was already serving a 116-year prison term — but now, an Athens, Georgia, man who shot and killed his girlfriend’s cousin during a police standoff was handed an additional life sentence in prison.

Senior Superior Court Judge Joe Bishop sentenced Nicholas Bernard Head, 30, last month to life without the possibility of parole for the shooting death of Quintavia Wade. Head was found guilty and convicted of malice murder and two counts of felony murder after a Clarke County Superior Court jury deliberated for less than two hours.

In October 2017, Head kidnapped Wade at her home in the Columbia Brookside housing complex off Hawthorne Avenue. Then, while holding the 28-year-old mother of two and an employee of a Bogart Caterpillar plant at gunpoint, the defendant requested to see his girlfriend Courtney Williams once more.

According to prosecutors, Williams and Wade were cousins and had been friends since their teenage years. Williams, who had a child with Head, was in a tumultuous and abusive relationship for years. Wade provided support for Williams after she ended the relationship.

During the trial, Williams testified on that fateful day, she went to the Clarke County courthouse to request a temporary protective order against the defendant. In September 2017, Head struck Williams with a crowbar and threatened her life with a knife to her throat after an argument over a phone charger.

Williams testified receiving a call from Wade later in the day telling her Head was at her residence with a gun pointed to her head. He had threatened to kill Wade, except Williams showed up at the residence. The police received a distress call minutes later from Williams informing them of Head’s actions and his location.

“He has a gun ... and if I don’t come he’s going to kill her,” said Williams to the 911 dispatch operator, according to OnlineAthens.

When the police arrived at the scene, they found Head holding Wade at gunpoint in the street with a 9mm pistol. Next, the defendant fatally shot her twice and then shot himself in the head, but survived and was taken to the hospital.

Before the trial commenced, Head was already sentenced to 116 years due to violating his probation for a 2016 charge. He was convicted on two counts of possession with intent to distribute cocaine, possession with intent to distribute marijuana, possession with intent to distribute a controlled substance, theft by receiving stolen property, possession of a firearm during the commission of a felony and obstruction of law enforcement.

According to Classic City News, as a first offender, Georgia law allows a defendant to be resentenced to the maximum allowed on each previous charge and serve a new sentence consecutively.

However, Head’s life sentence will be served concurrently with the 116-year sentence. Either way, he is unlikely to be in society ever again.
