Lea Michele is remembering Cory Monteith on the five-year anniversary of his death.
The actress, who has publicly paid tribute to him every year since his death, shared a picture of a sunset along with touching quote on Twitter.
“There are some who bring a light so great to the world, that even after they have gone, the light remains,” the quote read.
Cory and Lea, who first met while working on comedy Glee in 2009 began dating in November 2011 and were still together when he passed away.
The Glee actor, who died on July 13 2013 aged 31 and was found dead at a hotel in Vancouver, Canada, struggled with substance abuse for most of his adult life.
This time last year a documentary titled Autopsy: The Last Hours of Cory Monteigh aired in the UK and revealed that ultimately it was the combination of alcohol and heroin in his system that killed him
In the documentary, Dr. Jason Payne-James explained that the coroner concluded that Cory’s death was an accident and was aided by recreations of his death and crucial moments in his life.
The final coroner’s report said, “Mixed drug toxicity, involving intravenous heroin use combined with the ingestion of alcohol.”
The actor’s death was caused by a fatal mix of heroine and alcohol after a night out with friends.
Speaking in the documentary, Dr. Payne-James said: “Cory was tragically unaware that his central nervous systems was already compromised because of the amount of alcohol he had consumed throughout the evening.
“Within seconds after injecting the heroin the effects go these two drugs combined to suppress his ability to breath. As his breathing slows his heart has a much more difficult time pumping oxygen around his blood.
“Ultimately it was the alcohol and heroin in combination that killed him and not the heroin in isolation.”
However, it was actually his effort to defeat his “inner demons” and get off the drugs that helped cause his death.
From the age of 13 he skipped school and progressed from drinking alcohol to taking cocaine, crystal meth and ecstacy.
In 2001 at the age of 19 he was sent to rehab for the first time and returned many times during his life to break out of his drugs cycle.
And just 11 weeks before his death in April 2013, he came out of rehab again and was clean from drunks.
Dr. Payne-James explained that there was a “tragic irony” that the risk of a drug overdose dramatically increases in the first few months after leaving rehab.
He added: “Fresh from his month in rehab, Cory has lost the tolerance he built up after his long use. If drug users start back on the same drugs on the same level before they started rehab that can result in toxic and fatal consequences.
“The dose Cory was used to three months earlier would now have a much greater effect, suppressing his central nervous system that controls his breathing.”
