Former NBA star Jayson Williams tried to tamper with evidence minutes after his limousine driver's shooting death, according to a magazine report.

An unidentified witness told Sports Illustrated that Williams tried to put the victim's palm and fingerprints on the shotgun to make it look like a suicide, then threw away his own bloody clothes before authorities arrived.

Williams' brother reported the Feb. 14 shooting as a suicide to police.

Williams, 34, is charged with manslaughter in the death of Costas Christofi, 55, who was shot in Williams' bedroom. Prosecutors have said Williams was handling the gun recklessly.

Asked about the allegations in the magazine story, prosecutor Steven C. Lember noted authorities took the 911 call at 2:54 a.m., not 2:38 a.m. as the publication reported. "So that just proves that you can't believe everything you read in an article," he told The Associated Press.

Williams' attorney, Joseph Hayden, told the AP he would "address the relevant issues when we have our day in court." Williams' agent, Sal DiFazio, refused comment.

Christofi was hired to drive Williams' friends from a Harlem Globetrotters basketball game in Bethlehem, Pa., to a restaurant, then to Williams' mansion 30 miles northwest of Trenton, N.J.

About 12 other people were at the estate when the shooting occurred, including Williams' brother, two children and four Globetrotters.

Neither prosecutors nor defense attorneys have described the events leading up to the shooting. Neither side identified those inside the house at the time.

Several visitors, hearing the gun go off, rushed to the bedroom and found Christofi slumped against a wall, the magazine reported.

Williams screamed for someone to perform CPR and began pressing on the driver's chest, feeling for a pulse and talking to him, the magazine reported. A witness told the magazine Christofi "looked like he was in shock, then all of a sudden he was dead."

Two Globetrotters have been given immunity by prosecutors in exchange for detailed testimony, the magazine said. It did not identify the two.

In a statement, the Globetrotters said the players present during the shooting have been placed on paid administrative leave and were encouraged to cooperate with the investigation.

The 6-foot-10 Williams was among the NBA's best rebounders until leg injuries forced him to retire in 2000. He started working this year as a basketball analyst for NBC, but the network said last week that Williams will not make on-air appearances until the charges against him are resolved.

Williams did not enter a plea at Monday's initial court appearance and is not required to do so until a grand jury hands up an indictment.
