LOS ANGELES A former Los Angeles-area elementary school teacher has been charged with lewd acts on children, including putting cockroaches on students' faces, authorities said on Tuesday.
Mark Berndt, 61, was arrested at his home in the Los Angeles suburb of Torrance on Monday, accused of abusing nearly two dozen boys and girls, all of them ages 10 and younger, officials with the Los Angeles County Sheriff's Department said.
He is scheduled to be arraigned on Wednesday, the Los Angeles District Attorney's Office said in a statement.
An attorney for the former teacher could not be reached for comment. A message left at Berndt's home number was not returned.
Authorities began investigating Berndt over a year ago, after more than 40 photos depicting children in classrooms with their eyes blindfolded and mouths covered with tape were turned over to police, Sheriff's Department officials said.
"The details on this particular case are disturbing. There's no such thing as normal and this is way beyond normal," said Sheriff's Lieutenant Carlos Marquez, who supervised the case.
Authorities said some photographs showed girls being offered a blue plastic spoon that contained a clear or white substance, which authorities now believe may have been semen.
Early in the investigation, detectives recovered a similar blue spoon from the trash within the teacher's classroom that tested positive for semen, said Sheriff's Sergeant Dan Scott of the special victims unit.
Berndt's DNA was found to match that of the DNA profile found on the spoon, he added.
In some photos, Berndt was seen with his arm around children or his hand over their mouths, Scott said.
Investigators have discovered a total of 390 photos in the case, and about 10 of the children depicted in the photos have not been identified, the Sheriff's Department said.
The original group of photos turned over to detectives came from a company that does photo processing, such as the services offered at a typical drug store, Marquez said. Investigators did not name the company.
Investigators also recovered a DVD from Berndt's home depicting adult sexual bondage activity that mirrored the bondage-type photos of the children, Sheriff's Department officials said. The adults in the bondage video were not identified and the images in that video are not a crime.
For over 30 years, Berndt taught at Miramonte Elementary School in the Florence area of Los Angeles County, Scott said. Berndt, who taught third-grade, was fired by the Los Angeles Unified School District in early 2011, shortly after the investigation began, Scott and district officials said.
Berndt was formally charged on Monday with 23 counts of lewd acts upon on child, court records show, and was being held in jail in lieu of $2.3 million bail. He could spend the rest of his life in prison if convicted on all counts.
