The Associated Press reports that the Star-Ledger of Newark, The Record of Hackensack and several broadcast stations have said unidentified law enforcement sources told them ex-Nets Jayson Williams accidentally fired the gun that killed Costas Christofi early Thursday.

Williams was giving guests a tour of his 65-acre estate early Thursday when the shooting occurred.  Christofi, 55, of Washington Borough, had been hired by Williams to take friends from a charity sporting event featuring the Harlem Globetrotters in Bethlehem, Pa., to a restaurant, and then to Williams' home, about 30 miles northwest of Trenton.

Authorities have no immediate plans to arrest anyone at present, but might file charges in the future, a prosecutor said Saturday.
