endIndex: Emmy Award-winning journalist Samuel Burke takes us on a journey into the unexpected and sometimes dark side of DNA testing. Illustration by JL JAVIER For most of his life, Olongapo-born John Tompkins thought that the father who raised him was his biological one. Growing up with a Filipina mother and an American father in San Diego, California, Tompkins’s struggles usually had to do with his mixed ethnicity. His father, who worked for the US Navy, moved their family from Olongapo to San Diego when he was four. The story of Olongapo-born John Tompkins (center) — who thought that the father who raised him was his biological one — and Wayne Lane (second from right) from Alabama, is featured on the second episode of "Suddenly Family."
