Authorities say the physician husband of a radio host slain in Atlantic County in 2012 brandished a handgun as agents executed search warrants at his office and home.

A hostage negotiator persuaded Dr. James Kauffman to surrender Tuesday morning at his Egg Harbor Township office.

Atlantic County Prosecutor Damon Tyner says that Kauffman pulled out a Ruger 9mm gun when law enforcement officers raided his office. Kauffman allegedly pointed the gun at the officers and also threatened to kill himself. 

Tyner says that Kauffman was placed under psychiatric evaluation and was arrested on weapons charges, as well as possession of hollow point bullets.

The search warrants were issued as investigators probe "all leads pertaining to suspected criminal activity,” according to Tyner.

Kauffman’s wife, April Kauffman, was found dead inside her bedroom of their Linwood home on May 10, 2012. No one has ever been charged.

Tyner says that the raids conducted Tuesday were not linked to the slaying.
