The 1998 murder of Matthew Shepard shocked the nation.
Shepard, 21, was viciously murdered in Laramie, Wyo., where he was a college student. He was targeted because he was gay.
His death and the subsequent trial of his attackers stoked a new debate over gay rights. For many, it revealed the dangers of being gay in America, and for others, it reaffirmed the risk.
More than a decade later, Shepard's mother says there hasn't been nearly enough progress on gay rights.
Judy Shepard tells Neal Conan about her new book, The Meaning of Matthew.
