The Lt. Joseph J. Theinert 3-on-3 Basketball Tournament will be played at 1 p.m. on Saturday at the Shelter Island School to benefit the Lt. Joseph J. Theinert Memorial Fund, which supports programs for military families and veterans in need.
Lieutenant Theinert, who grew up in Sag Harbor and on Shelter Island, once played the sport at the Shelter Island School, wearing the number 15 jersey, which was retired last year. He was killed in action in Afghanistan on June 4, 2010.
