One household was forced to move due to smoke issues when their backyard was set on fire. One of the residents in that home was a pregnant woman.
The family told FOX 11 that they've had issues with fires being lit by people staying in the Santa Ana riverbed that borders the back of the property and that one of those people came to their home after the fire, telling them a woman was responsible.
