A Cape May County man pleaded guilty Thursday to a racketeering charge in connection with the shooting death of April Kauffman, Atlantic County Prosecutor Damon G. Tyner said.

Joseph Mulholland, 52, of Villas, pleaded to the second-degree charge before Superior Court Presiding Judge Bernard DeLury. Under his plea agreement, Mulholland could serve a maximum of 10 years in state prison.

Kauffman, a South Jersey radio personality, was killed in 2012. James Kauffman, an endocrinologist who was awaiting trial on charges that he arranged her death, died in January by suicide in a North Jersey jail. He allegedly was involved in a prescription drug-dealing scheme with the Pagans motorcycle gang and hired a hitman to kill his wife because she threatened to tell police.
