Newark, N.J. ? Former NBA star Jayson Williams jumped into the pool at his home while a friend disposed of Williams’ clothes after fatally shooting a limousine driver, according to an upcoming article in GQ.

The article, to be published in the magazine’s August edition, cites unnamed sources in recounting the night driver Costas Christofi died.

Williams had been in the bedroom of his mansion with Christofi early Feb. 14 when the shooting happened. The one-time member of the New Jersey Nets closed a Browning 12-gauge shotgun “with a snap of his wrist,” according to the magazine.

The weapon immediately fired, sending 12 pellets into the left side of Christofi’s chest, the article said.
