Toni Dykstra and Carlo Ventre met in sunny southern California in 1994 and fell in love. Soon after, a daughter was born but Carlo and Toni's relationship soured, leading to an international custody battle and charges of kidnapping.

Some four years later, Toni ended up dead in Carlo's Rome apartment. He said it was an accident; her family says it was murder.

Would Carlo be charged in the killing? What would happen to the couple's young daughter? Correspondent Bill Lagattuta reports on the investigation and heated legal battle that continues to this day.

In its unique approach, 48 Hours delves into a single crime, examining it from multiple angles with its saturation coverage and action-driven style. The broadcast has received critical acclaim reflected in almost 20 Emmy awards, a George Foster Peabody Award, and an Ohio State Award.
