Former Ala. teacher faces another sex abuse charge (AP) - A longtime Alabama schoolteacher accused of sexually abusing a fourth-grader has been charged with molesting a second female student. Danny Acker was charged Friday with an additional count of first-degree sexual abuse. He was arrested Thursday on allegations he molested a student before retiring in 2009. Police said he then confessed to molesting more than 20 girls over a long teaching career. "This is not a one-time event," said Deputy Police Chief Curtis Rigney. Authorities have asked anyone with information to come forward. The district attorney declined to comment on whether the new charge was a result of that request. An attorney for Acker did not return a message seeking comment. The first girl to make the allegations is now 12 or 13. She accused Acker of molesting her around 2009, when he was a teacher at Thompson Intermediate School. He remained on the school payroll as a substitute bus driver until this week, Rigney said. He was investigated on similar allegations in 1992, but grand jurors did not return an indictment, Rigney said. Acker's arrest stunned the Birmingham suburb of 28,000, where he was well-known and well-liked by kids. "Everybody knows Danny," former city councilman Bobby Harris said, shaking his head.
