Investigators believe a shooting that killed an 18-year-old inside a Spalding County home was accidental. But the suspected shooter was arrested in connection to his friend’s death, according to Griffin police.

Police were called to the Broad Street home late Monday and arrived to find a man dead on the couch, Lt. Michael Richardson said. Gideon Phazion Mays had been shot in the neck, Richardson said.

Mays was allegedly shot by Terrize Stroud, 23, while the two were visiting the home of another friend, according to police.

“While handling the weapon, somehow it discharged, striking the victim in the neck,” Richardson told WSB Radio.

Stroud cooperated with investigators, who determined the shooting was accidental.

Stroud was arrested and charged with involuntary manslaughter and reckless conduct, Richardson said.

In a separate and unrelated shooting late Monday, a 20-year-old man was charged with murder after allegedly killing his live-in girlfriend, according to the Spalding County Sheriff’s Office.

Deputies were called to a home on Railroad Drive in western Spalding County, where they found the body of Amber Nicole Clay, Sheriff Wendell Beam said Tuesday. Clay, 22, had been shot once in the head inside the home where she lived with her boyfriend, William Glen Spoon. Spoon, 20, was arrested and charged with Clay’s death, Beam said.
