Prosecutors say a New Jersey doctor accused of running an illegal prescription drug ring with a motorcycle gang and having one of the members arrange to kill his wife was himself the target of a death threat.

James Kauffman and four of six other defendants appeared in court Thursday via video.

Afterward, prosecutors said they have charged a co-defendant, Ferdinand Augello, with threatening to have Kauffman killed.

Kauffman has been transferred to a jail nearly 100 miles away for his protection.

He's charged with asking a Pagans Outlaw Motorcycle Gang member to find someone to kill his wife, radio host April Kauffman, in 2012.

Kauffman has long maintained his innocence.

A public defender representing Augello did not immediately respond to a request for comment.
