He told her he was a serial bomber.
According to federal court records, Dennis Mahon, was thumbing through an album of old pictures for the woman, showing off his Ku Klux Klan robe and other artifacts of his life when he began to tick off a list of places he claimed to have bombed since the early 1980s.
There was an abortion clinic, a Jewish community center and offices of the IRS and immigration authorities. He told the woman he liked to use a mixture of ammonium nitrate and fuel oil. He said he added powdered sugar to the mix for an extra bang. He would set off the bombs at 2 a.m., he said, so that no one was hurt but a message was still sent.
What Mahon didn’t know was that the woman he was bragging to was an informant working for federal law enforcement. And the trailer she was staying in was rigged with hidden cameras and microphones to catch every word.
