DEER PARK, Long Island -- There was a touching moment Tuesday night between a police officer and the woman who saved his life.
Gregory Holgerson is a police officer in Deer Park.
Back in 2012, he was diagnosed with a form of leukemia and in dire need of a bone marrow transplant.
It turns out a donor named Susan Hampton in Northampton, England was his perfect match.
He flew her in Tuesday night so he could personally thank her.
"If it wasn't for her I wouldn't be here right now. At the time when I got diagnosed, I had a two-week-old son and now I have a 3-year-old son and a 6-year-old daughter, and that's all extra time that I got because of her," Holgerson said.
Susan has a very personal reason for joining the bone marrow registry.
Her husband lost his mother to leukemia.
She encourages everyone to sign up to become a donor.
