n Allen argued that Gray was not irretrievably broken and sought parole eligibility to offer hope. Gray's grandmother, Debbie Polhamus, testified that his parents failed him and that his behavior had improved significantly after receiving medication and treatment in detention. Online mass shooter subculture The backstory: Investigators testified that Gray spent over a year planning the attack while deeply involved in an online group called the true crime community . Gray stored over 2,000 photos of Parkland shooter Nikolas Cruz on his phone and carved the number 38 into his rifle. During post-shooting jail phone calls, Gray excitedly asked his mother to look up fan art and social media commentary about him, prosecutors noted. District Attorney Brad Smith stated Gray placed deliberate Easter eggs on the day of the shooting to perpetuate his fame within the online subculture. District attorney addresses parents Why you should care: District Attorney Brad Smith warned parents that online true crime groups lack political ideology and are driven purely by nihilism and a desire to cause pain. Smith urged families to monitor what their children post on social media or display in their bedrooms and immediately remove access to firearms if concerning signs appear. Smith added that prosecutors did not charge Gray's mother because she lacked physical custody, lived in the county for only three months over two years, and did not supply the gun. Gray's father was tried separately after supplying the weapon, according to the district attorney. Post-trial legal options What we don't know: Official court records have not confirmed whether Gray will file a notice for a discretionary appeal within the 30-day post-sentencing window. Additionally, court officials have not indicated if Gray plans to submit a motion to withdraw his guilty plea. MORE
