The Brief Juan Rios was killed early Wednesday after fleeing CHP officers and crashing into a tree in Pomona. The chase ended around 2:15 a.m. when the vehicle lost control after hitting railroad tracks and slammed into a tree near Towne and Bonita avenues. California Highway Patrol officers attempted to pull over a Nissan Altima after observing the vehicle traveling without its headlights on. The driver refused to stop, leading CHP officers and local deputies on a pursuit down the freeway along the westbound 10. The sedan slammed driver's-side first into a tree outside an apartment building near Towne and Bonita avenues.
