A lawyer suing on behalf of three students who say they were sexually abused at a Los Angeles area school where two teachers have been arrested said Wednesday he represents nine victims and expects many more to come forward.

Three girls represented by attorney Greg Owen sued teachers Mark Berndt and Martin Springer, along with the principal at Miramonte Elementary School and the Los Angeles Unified School District on Tuesday, claiming intentional infliction of emotional distress, negligence, sexual battery and assault.

Owen said he intends to file four more lawsuits on behalf of Miramonte students this week and represents a total of nine clients in the still-unfolding case.

I believe there are many more victims, he said, adding that parents in the largely immigrant community have been reluctant to contact police.

Berndt, 61, was charged last week with 23 counts of lewd acts on children following a year-long investigation that began when bondage-style photos of students were turned over to police.

In some of the photos children were pictured with large, live Madagascar-type cockroaches on their faces, sheriff's officials say. In others students were seen with spoons of a substance later determined to be semen held to their faces, according to authorities.

Springer, 49, was charged on Tuesday with three counts of committing lewd acts on a child in what authorities say is an unrelated case involving a girl who was abused in 2009.

CASE TOUCHES OFF FUROR

The accusations have touched off protests by infuriated parents and prompted Los Angeles County school officials to temporarily replace the school's entire staff during an exhaustive investigation.

The school has been closed for two days during the transition and was scheduled to reopen on Thursday.

The three lawsuits filed on Tuesday accuse Miramonte's principal, Martin Sandoval, and the school district of allowing Berndt and Springer to remain in the classroom despite previous accusations against them by students.

The lawsuits also claim Berndt would take children from an after-school program and perpetrate heinous acts on them.

He was grooming children, grooming families. He would actually go to kids' homes, send the children letters, Owen said of Berndt. He would give them gifts. Books with notes inside on how they were special. We have all of that.

A Los Angeles Unified School district spokesman, Tom Waldman, said he could not comment on the lawsuits because the district's attorneys had not seen them yet.

The legal action came as reports surfaced that a former teacher's aide at Miramonte was under investigation over letters she wrote to an 11-year-old student there.

The Los Angeles Times reported the aide wrote in the letters she liked having the boy's arm around her and that she got the chills when he was close to her.

The school district fired the woman in July of 2009 for inappropriate behavior with students, Waldman said without providing further details.

Los Angeles County Sheriff's Sgt. Dan Scott declined to confirm the woman was being investigated.

We are looking into all leads that come forward, he said. Any information, any suspects, any leads we are prioritizing them and investigating any possible abuse that went on at that school.
