No. You just made that up, because you're desperate to be able to proclaim the existence of some sort of pattern of Sweden's "disappearing" people, as that's one of the few pieces of "evidence" you have left to prop up your laughable conspiracy theories about the sinking of the
Estonia.

Victims of enforced disappearance are people who have literally disappeared; from their loved ones and their community. They go missing when state officials (or someone acting with state consent) grabs them from the street or from their homes and then deny it, or refuse to say where they are. Sometimes disappearances may be committed by armed non-state actors, like armed opposition groups. And it is always a crime under international law.
These people are often never released and their fate remains unknown. Victims are frequently tortured and many are killed, or live in constant fear of being killed. They know their families have no idea where they are and that there is little chance anyone is coming to help them. Even if they escape death and are eventually released, the physical and psychological scars stay with them.
