The Neptune Beach teen accused of killing his grandmother is headed back to Florida, according to his attorney.

Prosecutors say Logan Mott, 15, stabbed and shot Kristina French, 53, then fled the state of Florida.

Officials were searching for Logan and his grandmother for days before they found French's body in a shallow grave in the backyard of Logan's father's home.

Officials say Logan had a bloody knife and three of his father's guns with him when he was captured on Nov. 24 while making a U-turn at the Canadian border.
