A brother's love brought him halfway around the world Friday night to San Francisco International Airport on a mission to save his little brother's life.
Five-year-old Colin McFadden has been diagnosed with a rare disease and needed a donor and that donor is his own brother who came from Vietnam.
Colin McFadden and his family drove from Nevada to SFO to meet his brother.
Colin was adopted from Vietnam when he was 14 months old and in 2011 his parents learned gravely ill.
"My bottom hurts and my back hurts," said Colin McFadden.
Linda Cross says doctors told them a bone marrow transplant was the only cure for their son.
"Never heard of aplastic anemia. Never thought it would happen to us," said his mother.
Asian bone marrow donors can be nearly impossible to find and match.
But Colin is lucky.
His parents had kept in touch with his birth family in Vietnam and right before Christmas they learned Colin's brother Tho was a match.
They anxiously waited with a welcome sign.
"Nervous to meet him. Excited, nervous you know," said Linda Cross.
Finally they saw him.
After 14 hours and nearly 14,000 miles Tho Van Luong gave his little brother a hug. They hadn't seen each other in years.
It was a difficult trip.
Tho's own two-year-old son had needed surgery which Tho couldn't afford until Colin's parents heard and decided to help.
"They' wouldn't operate because he couldn't afford it," said John McFadden. "So we insisted on paying for the surgery even though he didn't want to take the surgery, he said we needed to keep the money for Colin."
Tho's son recovered after surgery and now Tho is giving his brother the gift of life.
"He's giving Colin the one chance he has for a normal life and I just can't thank him enough," said Cross. "I don't know how you thank somebody for that. We're just really lucky, lucky and grateful."
Grateful for a bond that has brought two brothers back together.
Colin and his brother will go to Children's Hospital in Oakland and hope to have the transplant in mid-April.
Watchdogs are questioning an exclusive agreement between the City of Oakland and a non-profit group, tapped to lead a multi-million dollar project to redevelop the area around the Coliseum BART station.
