A man who was abducted as a six-year-old while playing in a California park in 1951 has been found more than seven decades later thanks to the help of an online ancestry test, old photos and newspaper clippings.

The Bay Area News Group reported on Friday that Luis Armando Albino’s niece in Oakland – with assistance from police, the FBI and the justice department – located her uncle living on the US east coast.

Albino, a father and grandfather, is a retired firefighter and Marine Corps veteran who served in Vietnam, according to his niece, 63-year-old Alida Alequin. She found Albino and reunited him with his California family in June.

On 21 February 1951 a woman lured the six-year-old Albino from the park in West Oakland, where he had been playing with his older brother, and promised him in Spanish that she would buy him candy.
