Almost a week after Harrison Wayne Olliff disappeared, Bulloch County Sheriff's investigators are still actively seeking the 21-year-old Olliff Road man. Olliff was last seen by a friend Thanksgiving night, and may have been going to Metter or Cobbtown when he left, said Bulloch County Sheriff Lynn Anderson. Investigators searched a four-county area over the past few days, using a helicopter as well as conducting searches on the ground, said Bulloch County Sheriff's Capt. Todd Hutchens.
