FLAGSTAFF, Ariz. -- A man suspected of starting a string of forest wildfires near Flagstaff isn't mentally capable of understanding the charges against him.
A competency hearing was held Thursday in a federal court in Flagstaff for 40-year-old Mark Mastin.
He was charged earlier this month with one count of burning federal land without a permit.
Authorities tracked Mastin through boot prints found at the fires' origin.
According to a criminal complaint, Mastin admitted to starting six of the fires, repeatedly apologized to authorities and offered to clean up the area.
The Arizona Daily Sun reports that a judge has decided not to allow Mastin to be charged with nine new counts of setting timber afire because he was mentally incompetent.
