Let us not forget Kayla Mueller, who was an American Human Rights Activist that was murdered by the Islamic State on February 6, 2015.
Kayla Jean Mueller (August 14, 1988 – c. February 6, 2015) was an American human rights activist and humanitarian aid worker from Prescott, Arizona. She was taken captive in August 2013 in Aleppo, Syria, after leaving a Doctors Without Borders hospital. Media had long reported that a 26-year-old American aid worker was being held by the Islamic State of Syria (ISIS) without naming her, at her family's request. Her captivity and death were widely reported upon confirmation of her death.
In October 2015, Kayla became the first person to be posthumously inducted into Northern Arizona University's college of Social and Behavioral Sciences Hall of Fame.
