Bradley Kollar, a 40-year-old from Hastings, Pennsylvania, loaded his SUV with explosives Tuesday morning and drove it into the home of William Shaner.
Police say Kollar killed himself and injured two unidentified men.
According to the Tribune-Democrat, Kollar believed Shaner "snitched" on his family for running a suspected chop shop and meth lab.
The explosion's aftermath has been described as a "war zone." One woman told the Tribune-Democrat she felt it four miles away.
Kollar was reportedly scheduled to be sentenced Tuesday morning.
