Andrew is the young man who was killed while witnessing to the unborn in one of the Crossroads cross-country walks. From the TAC website:

“Last summer, Kent, then a rising junior, participated in one of the Crossroads Walks Across America. Tragically, on the morning of July 20, 2012, he was struck and killed by an oncoming vehicle early one morning alongside a highway in Indiana. Since then, this shy, young defender of the unborn — who tirelessly prayed outside of abortion clinics when he was a student at the College — has become a hero to a generation of pro-lifers. In his honor, the Archdiocese of Washington, D.C., asked the College to prepare the above video to be featured at a youth rally prior to this year’s March.”
