All hints
Task 1
Hint 1
The article "Berserk Haunted?" mentions all the concerts where accidents happened. Don't forget the concert in Amsterdam as well.
Hint 2
Only one person was present at all the concerts where an "accident" happened. The tour poster and plane tickets excludes two people.
Hint 3
A blog post on meandberserk.blogspot.com excludes one person, and one of the interrogation logs excludes the last person.
Task 2
Hint 1
A yellow cap is mentioned in the handwritten lyrics, but it has been crossed out. The writer is therefore the person who owns the cap. According to Oliver Pilskog's interrogation, both William, Oliver, Leon and Runi wrote song lyrics, how can we find out which of them wrote this text?
Hint 2
The person who gave you the assignment asked you to check out a song. Search for the band on YouTube, Spotify, Apple Music or any streaming platform.
Hint 3
Listen to the lyrics of the song you found and compare it to the handwritten lyrics.
The article in "Give me Gossip" mentions who wrote all the texts for "The Oliver Pilskog Project".
Task 3
Hint 1
Read Runi Dahl's interrogation carefully.
Hint 2
Look carefully at the technical rider. The flame machine which had a technical failure has a red ring around it. How might this be related to what is said in Runi Dahl's interrogation?
Hint 3
Look at Runi Dahl's concert ticket and the map of the concert hall. Where was Runi?
Task 4
Hint 1
There is a somewhat unusual greeting in the anonymous letters.
Hint 2
If you cannot find this greeting in the evidence, can you look elsewhere? Where would you usually write such a greeting?
Hint 3
The police have done a poor job with censoring the personal info.
Where there's smoke there's fire.
