The amazing story of Katie Stubblefield: She became the youngest person to receive a face transplant

Katie Stubblefield had her whole life in front of her, but everything changed after her boyfriend broke up with her, aged 18. Tragically, the teenager shot herself, though by some miracle she survived. 

At age 21, Katie became the youngest face-transplant recipient in the United States and only the 40th person to undergo the surgery ever. It took more than 30 hours, but the surgeons did an incredible job and the young woman got a second chance in life.
