Nashville, Tennessee - Bob Bryar, the star drummer of rock band My Chemical Romance between 2004 and 2014, has died unexpectedly at the age of 44.

As TMZ reported Thursday, Bryar was found dead in his home in Tennessee on Tuesday. He was last seen alive by several passers-by on November 4.

According to the police, all the weapons and music equipment Bryar had at home were untouched, so officials do not believe any foul play was involved.

Two sniffer dogs were used to search the house, and Bryar's body was found in a decomposed state.

The cause of the prominent drummer's death is now being investigated by forensic experts.

Bryar first met the band members of My Chemical Romance in 2004 when they were on tour with The Used.

As the crew had some differences with their drummer at the time, Matt Pelissier, he was replaced by Bryar shortly after the release of the album Three Cheers For Sweet Revenge.

Among other things, Bryar contributed to the 2006 album The Black Parade, which is considered the group's best-known record, and co-wrote several songs.

Even before the release of 2010's Danger Days, Bryar left the group and initially worked with other bands in the years that followed before announcing that he would switch from the music industry to real estate.

In the years following his departure from the band, Bryar reported in online posts that he had struggled with suicidal thoughts on several occasions.

My Chemical Romance recently announced a North American stadium tour set to kick off next year, with all shows already sold out.
