Eleven years ago this week, Teresa Hall and her five-year-old daughter were murdered at their home in Jackson County Florida.
Sheriff's officials now say the mother and daughter may have died at the hands of a serial killer.
Tommie Lee Sales is on death row in Texas and has been linked to similar killings involving family members. Plus, he was reportedly in Jackson County in December of 1991 when the Hall murders took place.
Major Dennis has pledged to keep working the case until the killer is captured.
