At 7 a.m. today, searchers from state and local agencies planned to begin day three of their search for missing 13-year-old Griffin Prince. Griffin, who is believed to be somewhere under the surface of Lake Lanier near Buford Dam, went missing late Monday night after a fishing boat struck a pontoon boat carrying four families, including Prince and 12 other people. Griffin’s 9-year-old brother, Jake, was killed in the collision, which occurred around 10:30 p.m. Several other people were injured but not seriously.
