Jayson Williams, the former Nets player who faces another possible manslaughter trial for the death of a limo driver or a plea with prosecutors, was found acting "suicidal" and "violent" at the Embassy Suites Hotel earlier this morning. The Post reports Williams was taken to St. Vincent's for a psychological evaluation; a police source tells the Daily News (which says empty pill bottles were found in his suite), "He was barricaded, drinking, taking pills. He was overwhelmed. It all came crashing down." Apparently cops, who responded to a female friend's call, had to Taser Williams and needed two sets of handcuffs to restrain him. Back in 2002, limo driver Costas "Gus" Christofi was killed in a bedroom in Williams' sprawling NJ mansion; the Star-Ledger reported, "[Christofi] was inside, touring the house with the others [during a party], when Williams took out a loaded shotgun and snapped it shut in Christofi's direction. The gun discharged and he died within a few minutes."
