The search is on for a man who may be connected to yesterday's explosion outside the Colorado Springs chapter of the NAACP. The blast went off just before 11 a.m. FBI investigators say a device went off next to the outside wall of the building, which also houses other businesses. The person of interest authorities are looking for is described as a balding, white man in his 40s. He may be driving a dirty, white, 2000 or older model pickup. Nobody was injured in the blast.
