Washington Prep Principal Todd Ullah told KABC-TV that Angela Gettis was a good student and a leader on campus.

School district Superintendent John Deasy said Saturday that Angela Gettis was “a wonderful young lady” and added:

“It is a catastrophic loss for the school and for the community. My heart goes out to her family.”

Angela Kirkindoff, the student’s aunt said: “I just want people to remember the heart she had. She was very kind.”

A witness, Cameron Bonner, told City News Service the Washington Prep squad tied the game against Fremont in the fourth quarter when the cheerleader Angela Gettis collapsed.

Play was stopped as coaches and trainers ran to help the cheerleader Angela Gettis.

Cameron Bonner said: “They had just tied the game up, and the cheerleaders were pumped up.”

He added that Angela appeared “to just pass out”.

Bystanders performed CPR while waiting for paramedics to arrive.

“All of her friends were in a circle crying,” Cameron Bonner said.

Crisis counsellors will be at Washington Prep on Monday to help students and faculty deal with the death, Superintendent Deasy said.

An autopsy has been scheduled to find the exact cause of Angela Gettis’ death.
