'U.S. justice will find you' -victims' families on ISIS 'Beatle' sentencing

STORY: Elsheikh, who was born in Sudan and raised in London, was accused of conspiring to kill four American hostages: James Foley, Steven Sotloff, Peter Kassig and Kayla Mueller.

Four months ago a jury found the former British citizen guilty of charges that included lethal hostage-taking and conspiracy to commit murder.

Foley and Sotloff, both journalists, and Kassig, an aid worker, were killed in videotaped beheadings. Mueller was raped repeatedly by the group’s leader at the time, Abu Bakr al-Baghdadi, before her death in Syria, U.S. officials have said.

The deaths of Foley, Sotloff and Kassig were confirmed in 2014; Mueller's death was confirmed in early 2015.

Speaking with reporters following the sentencing, Foley's mother, Diane, said: "Let this sentencing make clear to all who dare to kidnap, torture or kill any American citizen abroad that U.S. justice will find you wherever you are, and that our government will hold you accountable for your crimes against our citizens."

The charges against Elsheikh, whose British citizenship was withdrawn in 2018, carried a potential death sentence, but U.S. prosecutors had previously advised British officials that they would not seek the death penalty.

Prosecutors argued that a life sentence was needed to prevent Elsheikh from causing future harm and to set a precedent that such crimes will get strict punishment.
