Guillen, 40, was fatally shot in the hail of bullets at the Route 91 music festival, according to a statement on a website raising donations for her family.
“She was a hard worker,” Marcus Guillen told KNBC in Los Angeles. “She was a fighter, a great mother.
Guillen worked as an assistant general manager at a pizza restaurant, and went to Katella High school in Anaheim.
