Swedish Prosecutor Closes Palme Murder Case

A long time ago, in 1986, the leader of Sweden, Olof Palme, was killed while walking with his family.

The police have been trying to find out who did it for a very long time.

They thought a man named Stig Engstrom might have done it, but they couldn't prove it.

Recently, someone asked to look at the case again using new science, but the person in charge of the case said there isn't enough proof to reopen it.

So, the case is closed, and the killer is still unknown.

Many people have different ideas about who might have done it, but no one knows for sure.
