Federal authorities have charged Ross Gordon Laverty with mailing an explosive device with intent to kill. Laverty was arraigned before U.S. Magistrate Judge Joseph Spero in San Francisco last Thursday. Court papers revealed that the 56-year-old Oakland man allegedly mailed bombs to a home in East Palo Alto on Oct. 19, and to an Alameda address on Nov. 24. Both bombs exploded.
