Daniel Montague Acker Jr., a former Alabama teacher, has been charged with molesting a second female student after being jailed on charges of sexually abusing a fourth-grade child, writes the Associated Press.
Shelby County District Attorney Robbie Owens said Daniel Acker, 49, was arrested on three counts of sexual abuse involving a student before he retired in 2009. After confessing to molesting more than 20 girls, police say he has now been charged with one additional account of first-degree sexual abuse involving a former student.
"This is not a one-time event," said Deputy Chief Curtis Rigney.
"This happened over a period of 25 years."
A girl of about 13 came forward last week claiming that Acker molested her when he was a teacher at Thompson Intermediate School in 2009, Rigney said.
Acker admitted to molesting the girl, and subsequently admitted to abusing more than 20 other girls but did not name any alleged victims.
Rigney says that Acker is no longer cooperating with investigators.
Acker has a history of sexual abuse allegations. Shelby County schools spokeswoman Cindy Warner said Acker was placed on leave in 1992 after a child abuse allegation was investigated.
After grand jurors did not charge him, the county school board voted against firing him. Warner says that he was reinstated as a fourth-grade teacher at Creek View Elementary, where he worked before moving to Thompson Intermediate.
Superintendent Randy Fuller said the district was cooperating with police.
"We can only say that the allegations are shocking.
"We, as a school district, understand that child abuse is horrible with devastating consequences to victims and their families."
Investigators believe most of the victims were members of Acker's classes, Rigney said. But police are investigating whether some of the girls were students in other teachers' classrooms.
"He was in a school. We don't know what contact he might have had with other kids," said Rigney.
The revelations and arrest has shocked the Birmingham suburb that Acker is a member of. He was well known within the community having taught for such a long time.
Former city councilman Bobby Harris said, "Everybody knows Danny."
