When the workers in hazmat suits arrived there wasn't much left to do.
Rosa Torres had received the mandatory 72-hour notice, posted on a tree beside her lean-to in the crescent-shaped median skirting North Hills Community Park.
She had moved about 20 shopping carts bulging with her belongings across Parthenia Place and deposited them in a nook just outside the park fence.
The workers sprayed some leftover debris with disinfectant and took it away in a big white truck, leaving the shopping carts behind.
Los Angeles Police Officer James McDonald, who monitored the cleanup, didn't think Torres would be gone long.
