"My son is a journalist, to the Middle East to report on the suffering of the people of Islam at the hands of the tyrant," Shirley, mother of Steven Sotloff journalist, said in the video appeal Drop son sent to rebel groups Islamic State (IS) last week. "I pray for the mercy and do not punish my son for the problems that it can not control." Sotloff reporter's mother said he was a journalist and is not responsible for the policies of the American government.

With a deep understanding of history and Middle Eastern culture, Sotloff, claiming to be "positive philosophers from Miami", has written articles for magazines such as Time, Christian Science Monitor, Foreign Policy and World Affairs Journal.

Sotloff friends also share intimate memories with some bad press. An academic writing on Twitter under the name Entropy Sotloff that is "close friends, like to joke, a funny teammate and fellow brave".

Other colleagues urged the public to remember about Sotloff by his work, not through video executions. "Let us stop, honor, remember and talk about Steven Sotloff.

Freelance journalist Ben Taub said Sotloff has suspended plans coverage but still want a last post about Syria. "He said that was pursuing a story but did not disclose the details," Taub wrote in The Daily Beast last month."Sotloff is experienced, careful and speak Arabic. Said he had enough things necessary."
