BERLIN - NOVEMBER 05:  Singer Joss Stone arrives for the 2009 MTV Europe Music Awards held at the O2 Arena on November 5, 2009 in Berlin, Germany.

LONDON -- Opening arguments in the celebrity stalking case of Joss Stone have revealed disturbing details about an alleged plot to murder the soul singer.

According to prosecutors, the two suspects, Junior Bradshaw, 32, and Kevin Liverpool, 35, armed themselves with a samurai sword, knives, a hammer, black bags and gloves, then set out from their homes in Manchester, U.K., for Stone's home in Devon, according to the Associated Press.

Handwritten notes found on the men said they planned to "decapitate" the singer. Another note read, "Jocelyn RIP," and a third read, "Once Jocelyn's dead...find a river to dump her."

A motive wasn't clear, but prosecutors suggest Stone was targeted for her wealth, and point out that the notes criticized her for being invited to the 2011 Royal Wedding of Prince William and Kate Middleton.

The defendants maintain their innocence.
