Nandi Hamilton, the mother of the victim, Taylor Hamilton, spoke to the local ABC station, WSB, stating that the group of teens was upset because Taylor was honoring her deceased boyfriend’s memory. This led to the confrontation that ended her daughter’s life in Clayton County.

Hamilton shared doorbell camera footage with WSB, depicting her daughter sitting quietly with her earphones on, awaiting her Uber, which was only minutes away.

Expressing her anguish and anger, Hamilton described the alleged shooter as a “monster,” condemning the act of violence as a senseless killing carried out in cold blood.

“He’s a monster,” Hamilton said about the alleged teenage killer. “He shot her in cold blood.”

According to WSB, the doorbell camera footage allegedly shows the 15-year-old taunting and getting upset with Taylor after a Thanksgiving gathering before brandishing a weapon. “I don’t care about no gun,” Taylor reportedly told him, before turning her attention away from the boy.

The teens allegedly taunted Taylor some more before she got in the shooter’s face, prompting him to open fire.

“I feel sorry for him that he’s that cold. To do something so monstrous,” Hamilton said, telling WSB that she believed her daughter was lured to the Thanksgiving gathering to be targeted. “I don’t know how he was that angry to pull out a gun and shoot her.”

The 15-year-old was arrested and charged with malice murder, first-degree child cruelty, possession of a firearm by someone under 16 and possession of a firearm during a felony. His identity is currently being withheld by police.
