US dad's custody fight threatening ties

Goldman has waged a four-year custody battle for his son, Sean, in Brazil. Goldman said he has not been allowed to see his 8-year-old son Sean since his former wife Bruna took the boy for a two-week vacation to her native Brazil in 2004 and never returned. Bruna remarried in Brazil and later died of complications from the birth of another child. (AP Photo/Eraldo Peres) (AP Photo/Eraldo Peres)
