The living donation chain began with Deputy Tracey Newton of the Riverside County Sheriff's Department.
Newton gave her kidney even though she didn't personally know anyone who needed the vital organ.
"Once you donate, your heart is kind of like The Grinch ... it expands a little more because you're like 'Wow, what more can I do?'" Newton said.
Her donation inspired three others to do the same. The eight people affected in the end were able to exchange flowers with each other during the reunion.
