Monteith, who starred as Finn Hudson on the TV series about a high school show choir, died July 13 at the age of 31 due to "mixed drug toxicity" of heroin and alcohol. Fox president Kevin Reilly had previously stated that "Glee" would air an episode in tribute to Monteith, addressing drug and alcohol abuse.
Murphy said the writing team for "Glee," which had been aided by Monteith's on-screen and real-life girlfriend Lea Michele, had originally planned to have Finn's character die of an accidental drug overdose, but they have decided against that idea.
"Basically, what we’re doing in the episode is we are not telling you yet, or maybe not at all, how that character died," he said to Deadline.com. "That might be weird for some people, but it felt really exploitative to do it any other way."
The cast and crew of "Glee," who have been working on a two-episode tribute to the Beatles, have found solace in being together following Monteith's death, Murphy said.
