A Hampton girl is being credited with bringing an Internet predator to justice -- and potentially saving the life of a friend. Jennifer Yeager, 12, a sixth-grader at Hampton Middle School, went to her friend's mother when she became concerned about the nearly yearlong relationship her friend had developed with a man on the computer. It progressed to telephone calls, sexually explicit conversations, him sending her nude pictures, and there was talk of meeting in person. Jennifer also helped police by telling them what she knew, the Pittsburgh Trib [1] reports.
