She was last seen with three men including van der Sloot, a 17-year-old Dutch national, after an evening at a nightclub.
Tragedy has brought the father of slain child beauty queen Jon Benet Ramsey and the mother of missing teen Natalee Holloway together for what they insist is friendship - but looks like a lot more.
Jurrian de Jong, 59, says he saw convicted murderer Joran van der Sloot carry Natalee's lifeless body into the building site and then return empty handed.
He says he did not come forward at the time of Natalee's disappearance because he was involved in Aruba's drug trade and was on the island illegally.
After the couple divorced in 1993, she raised her two children on her own.
In 2000, Holloway married George "Jug" Twitty, an Alabama businessman, and moved with her children to Mountain Brook, Alabama.
