Rocio Guillen Rocha

Guillen had given birth to her fourth child — a baby boy — just six weeks ago and was still on maternity leave from her job as a manager at a California Pizza Kitchen restaurant.

She and her fiancé, Chris Jaksha, both major country music fans, had traveled from their home in Eastvale to attend Sunday's concert as part of a birthday celebration for one of their friends, Jaksha's sister Nikki Stowers told NPR.

Stowers said that according to her brother, when the shooting began, Guillen was hit in the thigh. Jaksha was able to get Guillen to a hospital with the help of police, but she died soon after arriving.

Now Stowers is caring for the infant, along with the couple's 18-month-old daughter. Guillen's two older boys — one 13, the other 17 — are with Guillen's relatives.
