Police officer survives shooting, supports cause

Aurora police officer Ryan Burns in the hospital

In November 2014, our UCH trauma team treated Officer Ryan Burns, an Aurora policeman who was shot after pulling over a car. It took four surgeries and five units of blood to save Burns’ life.

Less than two months later, a recovering Burns was already giving back to the community that supported him by initiating a blood drive for City of Aurora employees. According to CBS Denver News, “Officer Burns asked to have this blood drive as a way to say ‘thank you’ to the community for supporting him, to the doctors and nurses who helped to save his life, and to the donors who gave their blood to help keep him alive.”

Eighty-seven people made appointments to give blood at this special event. For more details, watch the video on Yahoo! Screen. (An advertisement will play before the video.)
