GREENWICH - Three winners of last month's Powerball lottery jackpot came forward in a news conference today, deciding to jointly invest the massive prize. The men, Tim Davidson, Gregg Skidmore and Brandon Lacoff, were greeted at the state's lottery headquarters in Greenwich. They run an asset management company, and decided to create a trust fund for the $104 million lump sum. The original jackpot was $254 million before taxes. Lottery officials say Davidson bought the winning ticket at a BP gas station convenience store in Stamford.Powerball ticket worth $254M sold in Fairfield County
