>“This is a freak thing that never should have happened,” Zach Pettus, the brother of Matthew Pettus and half-brother of Sturm, told the Star Tribune. He said he couldn’t see any reason why anyone in the longtime group of friends would be targeted.
>“We knew something was wrong when [Sturm] didn’t respond to our messages,” he was quoted saying. “We have an idea who did it, but I don’t know if I should say something now.”
no reason they were targeted but they think they know who murdered them?
