Hi
@KathPlumber that was me
During the police interview GL tells the detectives that he used "a stack" and says he "put them in individually" so judging by his make of car he must have a CD player.
I can see two possibilities with this music situation:
1) GL was indeed playing his music loud in an effort to get RH & CC to leave their campsite so GL could continue illegally hunting deer or as a preemptive measure to drown out the sounds of the shooting he intended on doing.
2) RH & CC were playing their music, enjoying their evening wilderness retreat or perhaps to scare away any deer/be annoying so GL would pack up & leave
My issue with option 1 is that GL couldn't tell investigators what he was playing apart from that it was not from RH & CC's generation i.e "the most annoying" he could find.
My issue with option 2 is that I'm unsure if RH had a working car radio/stereo or what he may have been able to play music with. I also don't know if it's characteristic of him to antagonise GL with loud music.
