Relatives and friends of a missing Ohio woman will gather Monday morning to resume their search for her, her son and her friend.On Sunday, the woman's 13-year-old daughter was found gagged and bound in the basement of a Mount Vernon, Ohio, home.But the 32-year-old woman, Tina Herrmann, remains missing, along with her 10-year-old son, Kody Maynard, and her 41-year-old friend Stephanie Sprang.All four of them had been missing since Thursday.After her discovery, the teen -- Sarah Maynard -- was taken to a hospital for evaluation and treatment of non-life-threatening injuries, said Knox County Sheriff David Barber. Authorities had interviewed her "somewhat," he said, but would not divulge what was said. Police think she had been held since Wednesday, he said.The teen was recovered in an early morning raid on the home involving a SWAT team.Matthew Hoffman, 30, who lives in the home, was taken into custody after the raid, Barber said, and faces a kidnapping charge. Additional charges are expected, Barber said.A combination of intelligence received and investigative work led authorities to the home, Barber said. Authorities were hoping they would find all four people, but knew they might find only Sarah Maynard, he said.Police were still investigating whether Hoffman knew any of the four, he said. Asked whether Hoffman was cooperating with authorities, Barber said he was not.
