Kauffman was charged with arranging the 2012 killing of his wife, April, to prevent her from exposing an illegal drug distribution ring he was running with the Pagans biker gang.

Officials say in the summer of 2011, Kauffman solicited Ferdinand Augello to murder his wife because she was threatening a divorce and threatening to expose his drug enterprise which would cause him to “lose his empire.”

Kauffman had been the subject of death threats after his arrest, prompting his transfer from the Atlantic County Jail in Mays Landing, New Jersey, to the Hudson County jail nearly 100 miles north. Authorities said the switch was made for his own protection.

April Kauffman was found shot to death in May 2012 inside of their Linwood home.
