Story highlights Lawsuit: School district, three teachers, counselor and college indoctrinated girls

The alleged religious cult promoted martyrdom and celebrated death

The girls experienced "fantasies of suicidal ideation and martyrdom," lawsuit says

(CNN) A Connecticut family has filed a lawsuit claiming a public school district, a trio of high school teachers and others engaged in a "predatory religious indoctrination" that left their daughters speaking a "bizarre new language."

The 64-page federal lawsuit, which does not name the young women or their parents, claims three sisters attending Avon High School were targeted and indoctrinated without the knowledge or consent of their parents.

Two of the girls, now 22 and 19 years old, experienced sudden and severe personality changes, according to a lawsuit filed Tuesday.
