Islamic State 'Beatle' guilty of all charges in US hostage deaths
El Shafee Elsheikh, a member of the notorious Islamic State kidnap-and-murder cell known as the "Beatles," was found guilty of all charges on Thursday for the deaths of four American hostages in Syria.
A federal jury convicted Elsheikh, 33, a former British national, of eight counts after a two-week trial, the most significant prosecution of an IS militant in the United States.
