The WBC, which is known for its outspoken anti-gay views, praised Monteith's death as a sign from God.
Lea Michele and Chris Colfer were two of Monteith's co-stars on Glee, and Colfer is indeed gay both on the show and in real life. Michele, meanwhile, was dating Monteith at the time of his death, and a rumor spread on Twitter that the two were due to marry in a few weeks.
The Westboro Baptist Church left a special message on its Twitter account for her.
"Will @msleamichele kill herself as well?" the Twitter account asked. Then the wedding can go on as planned IN HELL! — invites for all their fans."
"PRAISE GOD ALMIGHTY for killing Cory Monteith - a wicked f**-enabling sinner!" the messages stated.
Already the Westboro Baptist Church is being criticized for its remarks, and this behavior from the WBC should come as no surprise. Earlier this year, the group held a protest at the funeral for Krystle Campbell, the 29-year-old who was killed during the bombings at the Boston Marathon. They had also announced plans to picket the funerals of the victims of the Sandy Hook Elementary shooting. However, Good Samaritans created a human wall during at least one of the funerals to block the protestors.
Cory Monteith returned to his hotel room alone on Saturday and missed his scheduled check-out time. Workers then went into the room to check on him and found his body. A cause of death has not yet been determined, but authorities do not suspect foul play. The 31-year-old had a history of drug problems and recently completed a 30-day stint in rehab.
It is still unclear how Glee will deal with the passing of one of its stars. Monteith's character, Finn Hudson, graduated high school at the end of Season 3 and spent much of the most recent season figuring out what he wanted to do with this life. He spent a brief time in the armed services before ultimately enrolling in college and taking on an assistant coach role in the glee club.
He did not appear in the final few episodes because of Monteith's rehab stint, but reports indicate that he was expected to play a large role in the first two episodes of Season 5, which have already been written. Early speculation claims that producers plan to dedicate the next season in his honor.
