On Monday morning, a popular photography teacher at El Dorado High School in Valencia, California was found hanging in her classroom by students, the Orange County Register reports.

According to police, 31-year-old Jillian Rose Jacobson was discovered at 8:40 a.m. after a teacher from an adjacent classroom unlocked the room for arriving students. The teacher then set Jacobson on the floor, where she was later declared dead by emergency personnel.

"The preliminary investigation indicates it was a suicide," a police spokesperson told the L.A. Times.

Former student Leo Amaya says the well-liked teacher "gave no signs of being depressed or sad" making her death especially shocking to the school community.

"She was just really involved in her students' lives," another student told KNBC. "She would ask everybody how their weekend was. If you were down, she would try to help you. She was just a very kind, loving person."
