The official account of the reality show congratulated the Nigerian contestant, who had impressed with her powerful voice and story.

Okwuchi had received a "yes" from each of the four judges after her Tuesday, June 6, 2017, performance.
On December 10, 2005, Okwuchi became one of the two survivors of the Sosoliso Airline Flight 1145 crash that took the lives of 107 passengers.
The crash occurred 20 minutes to landing on her way back to Port Harcourt for a Christmas holiday with other students from her school, Loyola Jesuit College.
After she shared her story with the audience and judges on Tuesday, Simon Cowell asked, "How do you deal with something like that, Kechi?’"
“Lying in the hospital bed with bandages from head to foot. Not being able to more or do anything else, music was my escape. And that’s why it means so much to me,” she said to the judges.
"I hope that maybe something is going to come out of this," Okwuchi said before she performed a tribute to the childhood and friends she lost over 10 years ago.
After over 100 surgeries, Okwuchi survived, and has remained positive and inspiring.
