A judge sentenced Colin Gray to 15 years in prison Thursday, following emotional testimony from victims' families during his sentencing hearing in the Apalachee High School shooting case.The sentence came after victims' families urged Judge Nicholas Primm to impose the maximum punishment, while defense attorneys argued Gray had sought mental health treatment for his son and asked for a lesser sentence. Judge Primm imposed a 15-year prison sentence after ordering most of Gray's sentences on the various convictions to be served concurrently, meaning they will overlap instead of being added together. Prosecutors sought an 80-year prison term."It is clear you failed as a parent," Primm said. "You didn't get him mental health counseling when it was obvious he needed some. None of those failures helped your case, but those aren't why you were convicted. You were convicted because the warning lights were flashing brighter and brighter and you didn't get him help."
