Just like other serial killers: "Jihadi John" is a cold loner, ex-ISIS fighter says

I'm not surprised at all by this BBC story:

The Islamic State fighter known as "Jihadi John" was a cold loner who set himself apart from others, says an IS defector who met him in Syria.

The BBC has spoken to a man who came across Mohammed Emwazi when he first arrived in Syria about two years ago.

Unlike other Britons, Emwazi wanted to appear in IS videos, the man said.

Emwazi, a Kuwaiti-born UK citizen, formerly from west London, has been named as the man in several IS videos where hostages have been beheaded.
