Note: Story does not contain any clues
You are a detective trying to find out the whereabouts of a very dangerous criminal. You have captured his accomplice, who refuses to give you any information. Luckily, you have found three different notes from the criminal that the accomplice had with him.
Tell your friends and family how much they mean to you,
Tell them...before it's too late.
Under the ground, a being stirs
Bringer of death, he strikes
Reaps your soul
Under the ground you go
All life must die
Ukuleles play the song of life
Am I alive or dead?
Funny how I don't know
Apache people live
Apache understand life and death like no other
Each note gives clues about how to solve the next one
After about 18 hours if this is not solved I will give another hint.
