Is Stureplansmorden coming back?

December 4, 1994 has been called the night when Stockholm's nightlife lost its innocence. At 5 o'clock in the morning, someone with an automatic weapon shoots straight into the entrance of the Sturecompagniet nightclub in central Stockholm. Four young people die and around 20 are seriously injured. The perpetrators, who were previously denied entry to the club, have come back for revenge. This year marks 30 years since the brutal shooting. Victims, witnesses, police, media and relatives talk about the event that left an indelible mark. What happened then?
