The child’s body was found when the vehicle was recovered.

Brown’s girlfriend, who was the child’s mother, told Gainesville police Monday that she and Lyrik were riding in a car with Brown when she got into an argument and physical altercation with him. She said they stopped and got out of the car and continued the altercation when he returned to the car and drove away, the child still buckled in her car seat.

Brown is in Cooke County Detention Center in Gainesville without bond, charged with assault with serious bodily injury relating to the altercation with his girlfriend.

Jail records do not list an attorney who could speak on Brown’s behalf.
