UPDATE: Logan Mott is back in Jacksonville at the sheriff's office Tuesday after being extradited from New York, according to JSO.
Logan Mott has waived an extradition hearing in Buffalo and will return to Florida to face murder charges for the death of his grandmother.
The prosecution says Florida authorities plan to pick up Mott on Monday, December 4. He will remain in custody in Buffalo on no bail until then.
Mott is accused of killing his grandmother, Kristina French.
"Logan is a good kid, with no previous history of anything, and he's my son and I love him," Mott's mother, Carrie Campbell-Mott said.
On November 22, police received a call about the disappearance of 15-year-old Logan Mott and his grandmother, 53-year-old Kristina French. Eric Mott, Logan Mott's father and French's son, is believed to have made the call.
Days after that call, the Jacksonville Sheriff's Office announced that they found French's body in a shallow grave in the backyard of the residence where they were reported missing from. She was shot and had multiple stab wounds.
Logan Mott was also detained by the U.S. Customs and Border Protection last Friday for trying to cross into Canada on the Peace Bridge near the Buffalo, N.Y. area, where he is currently being held without bond. He was found with three guns and a knife covered in what appears to be blood, police said.
On Tuesday, JSO issued a murder arrest warrant for Logan Mott in regards to French's murder.
