Jason Lance thought Jan. 21, 2010, was a day like any other until the call came.
He had dropped off his 9-year-old son, Montana, at Stewart's Creek Elementary School in The Colony, Texas, that morning.
"There were no problems at home. He was smart. He wore his heart on his sleeve and he talked and talked and talked," said Lance. It was "the same old, same old normal day. There were kisses and goodbyes and he said, 'I love you, Daddy.'"
