ADL offering $20,000 reward for information about Boston arsonist(s)

The first fire occurred last Saturday at the Chabad Center for Jewish Life Arlington-Belmont in Arlington, a Boston suburb, but did little damage and was put out easily. 

Last Thursday, a second fire started at the same location, and then approximately an hour later another fire started about 12 miles away at the Chabad Jewish Center in Needham.
