Dave Matthews Band dedicated the song “Mercy” to Steven Sotloff at a South Florida concert on Saturday, Aug. 1.

Journalist Sotloff, a former UCF student, was abducted by ISIS in August 2013 while traveling for work in the Middle East.

Matthews honored Sotloff Saturday night at the concert at Perfect Vodka Amphitheatre at the South Florida Fairgrounds in West Palm Beach, where Sotloff’s family was in attendance.

Students honored Sotloff in September 2014 at a candlelight vigil held at the UCF reflection pond.
