Task 1

DJ Knucklehead started his show later than planned because of the blackouts.
Task 2

Liam Nergård’s phone number is in his “personal info”
Can you find Liam Nergård’s phone number in Ida Oppdal’s phone log?
Task 3
Three of our suspects were there.

Trygve Runberg and Rune Eriksen were two of the three people at 7-Eleven. The last suspect tells us in their interrogation log that he/she was there.
Task 4
Some of the evidence material might have been touched by the suspects.
