A judge has ruled that a 13-year old girl is competent to stand trial after being accused of starting the Cocos Fire. In May the blaze burned about 1,995 acres and destroyed 36 homes in San Marcos, California, north of San Diego. The judge announced his decision in a hearing where the girl pleaded not guilty to four arson-related felony charges.

The Cocos Fire was one of at least 10 fires that burned in San Diego County during the same time period in mid-May.

During the proceeding the Deputy District Attorney told San Diego Superior Court Judge Rod Shelton that the girl’s parents, who were present in the courtroom, could be ordered to pay restitution in the case. County fire officials have estimated the costs of property damage and fire suppression to be about $12 million.
