SOMERVILLE, N.J. (AP) Former NBA star Jayson Williams ran naked from a bathroom in his New Jersey mansion and handed some clothing to an acquaintance after a hired driver was fatally shot, a witness testified Tuesday.

``He said, 'Here J.G.,''' John W. Gordnick, who has pleaded guilty to evidence tampering, testified at Williams' manslaughter trial.

Gordnick said he ``assumed'' Williams wanted him to get rid of the clothes, prompting an objection from defense lawyer Billy Martin.

Gordnick said he put the clothes in a black garbage bag, and placed it in his car, and put other clothing from Williams' bedroom floor in the car of another friend, Kent Culuko _ hiding both bags at a highway underpass.

Gordnick is the third witness to describe a chaotic scene after driver Costas ``Gus'' Christofi was hit with a single blast from a shotgun held by Williams on Feb. 14, 2002.

None were with Williams and members of the Harlem Globetrotters when the fatal shooting occurred; all three have said they saw Williams wiping down the shotgun.

Culuko also has pleaded guilty to evidence tampering, and to witness tampering. Dean Bumbaco, who testified Monday, was not charged.

In his testimony Tuesday, Gordnick recalled he was downstairs with his two young sons and John McPartland, a former professional basketball player in Europe, when they heard a ``thump.''

When the two men got upstairs, Gordnick said Globetrotter Curley ``Boo'' Johnson dashed past them ``probably running as fast as he can run.'' Gordnick said he found Williams in his bedroom.

``I saw Jayson on his knees with his hands on his head. I heard him a few seconds later, 'Oh my God, Oh my God,''' Gordnick said.

Gordnick said after his lawyer later persuaded him to give authorities the hidden clothing, he asked Williams if that would be a problem. ``He said, 'Absolutely not. You do whatever you have to do,''' Gordnick testified.

Also Tuesday, McPartland said guests at Williams' mansion agreed to make up a story _ that they were downstairs and Christofi had wandered off. A week later, McPartland said Williams urged them: ``You guys have to tell the truth and I'll have to deal with the consequences.''

Williams, 36, faces eight charges in the shooting, including aggravated manslaughter and witness tampering, that carry up to 55 years in prison.

The defense maintains the shooting was a complete accident, and that the shotgun was prone to malfunction. The prosecution charges Williams' actions showed recklessness.

Williams retired from the New Jersey Nets in 2000 after a decade in the NBA. He was suspended from his job as an NBA analyst for NBC after the shooting.
