A grand jury today indicted New Jersey Storm owner Jayson Williams on manslaughter and other charges connected to the killing of a limousine driver at Williams' estate earlier this year.

Prosecutors charged Williams with aggravated and reckless manslaughter, aggravated assault, evidence tampering, witness tampering, hindering apprehension, and fabricating evidence in the 14 February shooting of Costas Christofi at Williams' Alexandria, NJ estate.

Williams allegedly shot Christofi in the chest with a 12-gauge shotgun while giving guests a tour of his house, then asked others in the house to give false statements to investigators, making the death appear to be a suicide. The indictment said that Williams was mishandling the gun when it discharged.

John Gordnick, who was at the house at the time of the shooting, was also indicted, on charges of evidence tampering and hindering apprehension. Prosecutors allege that Gordnick helped Williams make the shooting appear to be a suicide.

A third man, Kent Culuko, avoided indictment on similar charges by reaching a plea agreement with prosecutors last week. His record will be expunged in exchange for pleading guilty, agreeing to testify against Williams and Gordnick, and performing 250 hours of community service.

Aggravated manslaughter carries a sentence of up to 30 years, reckless manslaughter ten years, and the obstruction of justice charges combine for more than ten years.

Conviction on the aggravated manslaughter charge requires prosecutors to prove that Williams had shown "extreme indifference to human life."

Steven Lember, acting Hunterdon County prosecutor, said at a press conference today that alcohol "is something we need to look into," but stopped short of speculating on whether Williams was intoxicated at the time of the shooting.

Williams remains free on $270,000 bail since a March court appearance on the charges, during which he was not required to -- and did not -- enter a plea. He must do so when arraigned on the indictment, at a date to be determined.

Williams' attorney expressed pleasure that the case is now headed to trial.

"We remain confident that after a full exploration of the facts the truth will show that the death of Mr. Christofi was a tragic accident but not a criminal event," Joseph Hayden said.
