Four For Friday - Getting Back

 He really wanted to get back in the good graces of the band that fired him. He went from making lots of money and attending the best parties, to just being a hanger on. He knew the band wanted full control of their name. He knew there was a battle going on. He asked one of his friends to help him, but the friend said no. What did he need help with? Killing a fired member of the band. There would be one less person who could claim the name of the group. The friend did agree to be there at the killing, but refused to actually do anything untoward. Hey, not reporting the murder is pretty untoward. Our killer managed to pin the blame on the friend. The killers also got a relative of the friend to accuse other band members of the murder.
