A deaf woman living in a house in the central valley did not know her home was on fire Tuesday night until a neighbor broke in to rescue her. The fire occurred around 11:15 Tuesday night at 4516 Mark Ave. No one inside was injured, but a firefighter did suffer a cut to his hand and was hospitalized. The fire started in the back yard and spread up the back side of the house and into the second floor. Flames and thick, dark smoke billowed from the home. The cause of the fire is not yet known.
