GRANGER — Agents of the FBI and the federal Bureau of Alcohol, Tobacco and Firearms are now investigating at least four reported incidents of explosive devices found in Granger mail and paper boxes and the possibility that they could be connected.
One of the "bottle bombs" exploded Monday inside a Penny Saver box at the home of Brendan Mullen, a Democrat running against Jackie Walorski for the 2nd District congressional seat. Mullen said he actually saw a black car pull up to his paper box around 4:45 p.m. Monday, put something inside and speed off.
