MARTINEZ -- Prosecutors added 16 more sexual abuse charges against a former Concord elementary school teacher Tuesday, raising his total to 125 counts involving 13 former students.
Joseph Martin, the former Woodside Elementary School teacher, also had his preliminary hearing waived and will go to trial, said Contra Costa deputy District Attorney Derek Butts.
The victims are all male students who were once in his fifth-grade class dating back to the 2006-07 school year, Butts said. No new victims were discovered, the prosecutor said; however, while reviewing a large volume of police reports, Butts found additional allegations to be charged.
Martin -- who has pleaded not guilty and is in custody on $10 million bail -- will face a second formal arraignment Sept. 23. The popular teacher, known for his unorthodox teaching methods that included producing and filming classroom plays, faces life in prison if convicted.
Martin worked in the school district since 1991.
Two civil actions have already been launched against the teacher and district administrators. The families of two boys claim district officials knew of early complaints about Martin's conduct and that no one reported them to police or Child Protective Services, as required by state law.
