The US hostage allegedly killed in a Jordanian air strike against Islamic State militants is understood to be 26-year-old Kayla Mueller, from Prescott, Arizona.
Ms Mueller travelled to the Turkey-Syria border in 2012, to work for the Danish Refugee Council and Support to Life, according to her family.
On 4 August, 2013 she was taken captive by IS in Aleppo, Syria, while leaving a hospital run by MSF (Doctors without Borders).
During her aid work, Ms Mueller visited refugee camps where she played and painted with Syrian children.
She found that she “can’t do enough” to help Syrian families, according to a report in her local Arizona newspaper, The Daily Courier.
“When Syrians hear I’m an American, they ask, ‘Where is the world?’ All I can do is cry with them, because I don’t know,” she told the newspaper.
Ms Mueller said she heard stories of children being hurt by unexploded bombs, women being forced into early marriages, and children being forced to fight for both sides.
“Syrians are dying by the thousands, and they’re fighting just to talk about the rights we have,” Mueller told the newspaper.
“For as long as I live, I will not let this suffering be normal. (I will not let this be) something we just accept,” she said.
Ms Mueller studied at Northern Arizona University, in Flagstaff, where she volunteered for three years with the Save Darfur Coalition.
She wrote letters and placed calls to members of Congress, and took part in silent protests, according to a separate profile in the Daily Courier.
After graduating in 2011, she lived and worked with humanitarian aid groups in northern India, Israel and the Palestinian territories, her family said.
She then returned home to Arizona and worked for one year at an HIV/AIDS clinic while volunteering at a women’s shelter at night.
In December 2011, she travelled to France to become an au pair so she could learn French in preparation for work in Africa. It was there in 2012 that she decided to go to Syria, her family said.
“The suffering of the Syrian refugees drew Kayla to the Turkish/Syrian border… to assist families who had been forced to flee their homes,” said her family in a statement.
“Kayla found this work heartbreaking but compelling; she is extremely devoted to the people of Syria.
“The common thread of Kayla’s life has been her quiet leadership and strong desire to serve others.
“When asked what kept her going in her mission, she said: ‘I find God in the suffering eyes reflected in mine. If this is how you are revealed to me, this is how I will forever seek you.'”
As you probably already know I have nothing but contempt for these sanctimonious social justice warriors we see blocking freeways and disrupting restaurants and stores with their protests. They treat protesting like a fad or hobby and have no real plan or concrete goals other than seeking attention.
I’m guessing I wouldn’t have agreed with the political beliefs of Kayla Mueller, but she was no dilettante playing at saving the world between shopping and fancy dinners. She put her life at risk, endured hardship, and tried to help people in real need.
Unfortunately, it got her killed.
She may have been naive and misguided politically, but she was sincere in her desire to help people. The world could use more people like Kayla Mueller.
Rest in peace.
