“It takes on a little bit of a different tone right after the loss of a very young officer who also just graduated from the academy,” Davis Police Chief, Darren Pytel said.

O’Sullivan, 26, was one of the cadets just a few months ago. Wednesday night, she was killed while responding to a domestic disturbance call.

“Following the death of an officer there’s just such an overwhelming feeling of loss and sadness,” Pytel said.

“Tonight we get to celebrate. Tomorrow we get to grieve and it’s okay to have joy within sorrow. It’s okay that we take time to be able to do this because this is what will re-frame the sadness,” Russell said.

Officer Natalie Corona’s family also attended the ceremony. She’s graduated in the previous academy and was killed earlier this year in the line of duty in Davis.
