Flint, Michigan (CNN) -- A few weeks ago, Nicole Mansfield called her daughter in Flint, Michigan. She tried to calm Triana Jones down, but she had bad news. 

"She said, 'I might not be home in a week, somebody stole my ID,' " Jones recalled of the conversation almost a month ago. "So she wasn't able to come home." 

This wasn't a minor headache, part of the travail of international travel. Jones thought her mother could be in Syria, fighting alongside rebels in the country's bloody civil war. 

Nicole Mansfield had converted to Islam several years ago, her daughter told CNN Friday. 

Jones wept as she and Gregory Mansfield -- her mother's father -- talked to CNN about the horror they felt seeing images on the Internet this week of a dead woman they are convinced is Nicole Mansfield. 

Syrian state-run television aired a story saying that government forces had killed three Westerners. The video package shows a bullet-riddled car, weapons placed on the car hood, a computer, a hand-drawn map of a government military facility and a flag belonging to the al Qaeda-affiliated al-Nusra Front. 

The camera pans close to bodies arranged in a row, lying on the ground. 

Mansfield's relatives told CNN they have no doubt she's one of them. 

Though it's unclear how the family knew to look on the Web to see the images, they say the FBI paid the Mansfield family a visit Thursday to ask them about reports that Mansfield was killed in Syria. 

"The first time I saw those pictures I had to look again because I didn't even recognize her. I didn't believe it was my mom the first time I saw them," Jones told CNN, choking back tears. "And then I had to look again and I looked at her body and her feet and her hands and her nose and her mouth. And I knew it was her."
