Story highlights A photography teacher is found dead at El Dorado High School in Placentia

Another teacher and students found her in a classroom

(CNN) A photography teacher at a Southern California high school appears to have committed suicide by hanging herself in a classroom.

Jillian Jacobson, 31, was found Monday at El Dorado High School, said Lt. Eric Point, with Placentia Police. There was no indication of foul play, and every indication that she took her own life, he said.

According to Steve Concialdi with the Orange County Fire Authority, students had been waiting outside the classroom to get in. Another teacher opened the door.

When they went inside the classroom, they found Jacobson hanged. They quickly brought her to the ground and called 911, said Concialdi, but she was declared dead at the scene.
