A 49-year-old Yakima woman accused of setting her mother's home on fire Sunday possibly faces charges of first-degree arson and violating a no-contact order.
The woman made a preliminary appearance Monday in Yakima County Superior Court.
Yakima County Sheriff's deputies responded to the call in the 3500 block of Birchfield Road about 12:40 p.m. Sunday and found that the fire had been extinguished by those at the scene, according to a probable cause affidavit.
Sunday morning, the woman pointed a knife she was using to chip ice at her mother and threatened to kill her, the affidavit said.
The woman was at her mother's home in violation of a no-contact order, the affidavit said.
Later, the woman went outside, where a loud noise was heard. Family went outside and saw the porch on fire and flames shooting from a propane tank next to a grill, the affidavit said.
There were three people inside the home including the woman's mother and son at the time of the fire, the affidavit said.
