While the neighbors have seen increased suspicious activity, one homeowner saw a lot more. Arturo Jose Luis Estrada removed a window screen and then broke the kitchen window to the home. Bluntly, I don't understand why you carefully remove the screen only to break a window but whatever. The homeowner heard the commotion, grabbed and handgun and encountered Estrada.
Was it a friendly hello? Offer him tea and crumpets? Nope, he fired multiple rounds and struck Estrada at least twice. Estrada fled the house and was seen leaving the area with a Hispanic woman with black hair (that description should narrow it down a lot!). Of course, bullet wounds and running aren't really symbiotic so Estrada made it half a block before collapsing.
Police were called, took Estrada into custody and over to Kern Medical center with gunshot wounds to the chest and arm. Estrada was treated and will be taken back into police custody upon his arrest.
This being California, police are still looking into charges against the homeowner.
