GRESHAM, Ore. – The mom of a Gresham shooting victim struggles to comprehend how a simple request to turn down music could end in her daughter’s death. “Shooting her was completely senseless. I can understand arguing or yelling or something like that, but to shoot somebody just because you’re told to turn down your music, that’s just unbelievable,” said Rhonda Henson, whose daughter Susan was fatally shot during a confrontation over loud music.
