A 44-year-old man was arrested after he failed to register as a sex offender, according to the Bulloch County Sheriff's Office. Terry McCollum was charged with failure to register as a sex offender after the sheriff's office received "a tip by an alert citizen," which prompted an investigation by Capt. Todd Hutchens, Sheriff Lynn Anderson said in a news release issued Wednesday. McCollum was required to notify the sheriff's office of changes to his residence and employment based on a 2000 conviction in North Carolina for taking indecent liberties with a child, but he did not make those notifications after making recent changes to both, Anderson said.
