One fan spoke about the impact his character on Glee, Finn Hudson, had on their adolescent years.
"Glee, and namely Finn Hudson, were a huge part of my growing adolescent years. Losing Cory Monteith felt like losing a part of my childhood. I'm so thankful for the happiness he brought me and will forever miss him."
The Canadian actor was found dead in his Vancouver hotel room six years ago. Toxicology reports found Monteith died as a result of a combination of heroin and alcohol in his system. Authorities ruled the death as accidental.
Earlier in 2013, Monteith had checked into rehab over substance abuse issues, which dated back to his teenage years.
