Leland Cobain, the grandfather of late Nirvana frontman Kurt Cobain, has died at the age of 89 in Montesano, Wash. The senior Cobain reportedly passed away on Wednesday (May 29), according to GrungeReport.net. No cause of death was given.

Leland Cobain was a huge fan of his grandson, and according to a Seattle Weekly feature in 2010 he kept a shrine to Kurt in his double trailer. Among the items in his home were a gold plaque given to Nirvana, a Kurt Cobain action figure and many photos taken from Kurt's youth. The elder Cobain was one of the few surviving members of Cobain's family willing to speak about the late rocker and corresponded with fans from around the world about his grandson.

However, his open nature speaking about Cobain's life also led to a rather strained relationship with his other relatives. Leland Cobain also spoke frequently about the theory that his grandson was murdered and did not commit suicide. A video feature with Cobain speaking about Kurt can be seen below.
