Friends and strangers alike offered their support Thursday for a grieving Buford family, even as crews continued to search a third day for 13-year-old Griffin Prince, who has been missing since Monday’s fatal boat crash. Griffin’s 9-year-old brother, Jake, died on the scene of the crash, which involved a 21- to 22-foot center console fishing boat and a 17-person pontoon boat carrying 13 passengers on Lake Lanier. The fishing boat struck the pontoon practically head-on in the Shoal Creek area of the lake near Buford Dam, according to authorities.
