(CNN) -- Just over a week ago, they were two little boys living with their grandparents and the family dog, Nati, in Tampa, Florida. That was then. First, police say Chase and Cole Hakken's father broke into the home and tied up the boys' grandmother before whisking the two children away -- one day after he and the boys' mother officially lost their parental rights. The 2- and 4-year-old boys ended up sailing to Cuba with their parents, triggering an international manhunt that ended this week. Chase and Cole are now back in Tampa, trying to resume their life with Nati and their grandparents.
