Thomas Day Jr., 54, of Riverside, California, was with his four children at the festival, said Bruce Abbey, a vice president of a California construction company where Day worked.

His daughter Whitney Day wrote the following about her father:

“My sisters Candice and Kelsey and brother Nolan and I just want to say that he was our rock, he was our everything. Anyone he came across he put a smile on their face. All our friends would call him Daddy Day because he treated everyone like one of his own and it was an honor to us all to be able to share our dad with the world.”

Day was an estimator at Portrait Construction in Corona, California, and had been at the company for more than 20 years, Abbey said.
