After years searching, I found my sister next door

Hillary Harris and Dawn Johnson were strangers who shared a driveway - until Hillary made a life-altering discovery.

From a young age, Hillary knew she was adopted but later in life couldn't find her biological half-sister, Dawn.

She didn't expect her to move in next door, in their Wisconsin suburb.
