>> reporter: desperate to get away, she and her friend crawled into a home furnishing store and hid with 15 other people in a back room. they could hear the terrorists just one floor above.
>> i could hear more machine guns and shooting in the background. that's when i realized this was a serious situation.
>> reporter: after more than five hours she says out of nowhere a security team showed up looking for her and her colleague. she is certain they were american.
>> this american security forces guy came back and said if you want to get out, we understand it's dangerous but this is probably your best shot.
>> reporter: as they ran from the mall, more gunshots and explosions.
>> we were walking out of the store and all of a sudden all of this gunfire starts on the first floor and there's just bullets. we start walking about 20 feet and then, like, within like 30 feet of us two grenades are thrown. that part was the worst. we thought it was over. we're out of the woods.
>> reporter: while hiding she texted her father. in an active shooter situation, please pray. back home, her mother terrified had written it all down.

>> reporter: she isn't sure if she'll ever return to kenya. as for the security team that rescued her we checked with the pentagon, the state department , and the world bank , all of them say they didn't have any security teams on the ground. so it's not at all clear who rescued her and exactly how it all went down. guys, back to you.
