Steven Sotloff's family breaks silence over son's death
Barak Barfi speaking outside the family home in Pinecrest, Fla., said Sotloff was not a "war junkie" but wanted to give a voice to those who "had none."
Barfi also called the writer a "hero," adding, "he ultimately sacrificed his life to bring their story to the world... He had a gentle soul that this world will be without."
On Tuesday, a video was posted online purporting to show the beheading of the journalist.
U.S. officials confirmed the authenticity of the video Wednesday.
A memorial was set for Sotloff at 1 p.m. Friday at Temple Beth Am in Pinecrest, Fla.
