Fresno County Sheriff Margaret Sims said two other gunmen were arrested and three remained at large following Thursday's pre-dawn violence.
She said deputies heard the sound of gunfire as they responded to calls of a robbery at a house south of Fresno. They saw two cars speeding away and were only able to stop one when it pulled up to a hospital with a wounded man in a ski mask.
Suspects in the other car took the girl hostage and dropped her off near downtown Fresno.
Another robber found near the house later died of gunshot wounds.
