A Millen man and former Statesboro-area radio personality remained behind bars Friday after a four-hour standoff Thursday during which police said he held his wife at gunpoint in their home. Nearby schools were placed on lockdown as a precaution while Rick Pittman, 57, of Bay Street, remained barricaded in his house as Georgia State Patrol SWAT officers and other law enforcement agents stood by, Millen Police Chief Dwayne Herrington said. Pittman and his wife, Linda Pittman, reportedly had a domestic argument when Rick Pittman allegedly pulled a handgun and held her against her will, Herrington said.No one was injured, but as a safety measure, schools were locked down until it was time for students to be released.
