A 33-year-old Titusville man suspected of killing his mother during a dispute -- the ninth case of homicide for the Space Coast since Christmas Eve -- is being held without bond at the Brevard County Jail Complex. Sheriff’s investigators said Main battered his mother at a home on La Grange Road north of Titusville. Deputies determined that a domestic dispute had taken place, leading Main to attack his mother. A public defender was appointed for Main, court records show. A court hearing for Main has been scheduled for March 11 at the Titusville Historic Court House.
