SAN DIEGO (AP) — A judge on Wednesday ruled that a 13-year-old girl is competent to stand trial on allegations that she deliberately started a wildfire that destroyed three dozen homes north of San Diego in May. The judge made the ruling in a brief hearing in juvenile court, where the girl pleaded not guilty to three felony counts of arson and one misdemeanor count of unlawfully allowing a fire to escape from one's control. While the district attorney's office didn't mention a dollar amount, the U-T reports that official estimates have put the cost of fighting the fire and lost property at $12 million.
