Police in New Jersey are trying to determine who fired a bullet that struck CNN commentator Lou Dobbs' home as his wife stood nearby.

State police Sgt. Stephen Jones says Dobbs' wife and driver were outside the home Oct. 5 when they heard the gunshot. Jones says the bullet didn't penetrate the siding and fell to the ground outside.

Dobbs mentioned the bullet earlier this week on CNN and his radio show and says he had been receiving threatening phone calls for weeks. On his radio show, he connected the gunshot to his advocacy for a crackdown on illegal immigration and to his opponents' rhetoric.

The home is on a farm in Wantage, about 50 miles northwest of New York City.

'THRILLER' COLLABORATORS SUE FOR $2.3M

Michael Jackson's collaborators on "Thriller" say they are due more than $2.3 million from the singer's estate.

George Folsey Jr., the producer of the iconic 14-minute "Thriller" video, filed a claim in Los Angeles yesterday for more than $1 million he says he's owed.

An attorney for the video's director, John Landis, filed creditors claims against the singer's estate — also yesterday — saying they are likely due more than $1.3 million. Landis and his company sued Jackson before his death, claiming the singer hadn't paid Landis his share of profits in recent years.

Landis also sued to stop Jackson from exploiting new "Thriller" projects, such as a Broadway show. Those cases are still pending.

1967 WARHOL SELF-PORTRAIT UP FOR AUCTION

Sotheby's is auctioning a self-portrait by Andy Warhol that was recently found after being forgotten in a closet in New York City for more than 40 years.

The painting belongs to Cathy Naso. She was 17 years old when she got a part-time job as a receptionist at Warhol's Factory. Two years later, in 1967, Warhol gave her a self-portrait inscribed to her.

The Brooklyn resident displayed the painting briefly and then stored it in a closet, where it stayed until this year. The auction house estimates it will sell for $1 million or more.
