A firefighter climbs on a ladder during efforts to extinguish burning row houses in Coatesville, Pa. on late Saturday, Jan. 24, 2009. This was the latest in a string of suspicious fires in this Philadelphia suburb. At least 30 arsons have been reported in the area since the beginning of 2008, about half of them in the last three weeks. There was no clear information who was committing the crimes or why.
