As heavily armed agents converged Friday on a wooded area where abortion clinic bombing suspect Eric Rudolph resurfaced last week, questions remained about his contact with a man he obtained supplies from.

Rudolph went to the home of a health food store owner twice, a law enforcement source speaking on condition of anonymity told The Associated Press.He went to George Nordmann's house on July 7, when he showed up and got food, and two days later when he appeared again, requested specific items and departed in Nord-mann's truck, the source said. He reportedly left five $100 bills as payment for provisions including oatmeal, raisins, tuna, dried fruit and batteries.

On July 11, two days after the second contact, Nordmann, 71, notified authorities. His truck was found Monday at a campsite a few miles away from his home 10 miles east of here near Nantahala Lake in far western North Carolina.

Media reports said a note left on the front seat - The Birmingham News said Friday it was in Rudolph's handwriting - stated who the truck's owner was.

Federal agents have refused to comment about Nordmann, his role and what investigators found when they searched his truck. Nordmann's business in Andrews has been closed all week, and he does not appear to be at his home.

Rudolph, 31, is accused of the Jan. 29 bombing of a Birmingham, Ala., abortion clinic, which killed an off-duty policeman and severely wounded a nurse. He also is wanted for questioning in three Atlanta-area bombings, including the 1996 Olympics blast that killed a woman and wounded more than 100.

Since Norman's truck was found, more than 200 federal and state officers have arrived to search for Rudolph, an experienced out-doors-man.

Searchers had concentrated on a range of hills 10 miles east of Andrews, but on Friday the hunt shifted a few miles north to Otter Mountain, behind Nordmann's home.

Sheriff's deputies set up roadblocks along the road where Nordmann lives, as a U.S. Customs Service helicopter with infrared and heat-sensing equipment flew overhead searching for Rudolph.
