Pearl Jam is one of the last great stalwarts of the 90's era grunge revolution, but even their years of experience in the music industry can't protect them from being bilked, as the case of their former manager Rickey Charles Goodrich proves. 

According to the New Music Express, Rickey Charles Goodrich admitted that he had stolen large amounts of cash from the grunge group during the four years that he had served as chief financial officer for Pearl Jam's management company Curtis Management. Members of the band had hired a private investigator to look into Goodrich's "cash flow issues" and subsequently discovered records for a number of transactions and wire transfers that had been used to pay off his personal debts. The group have not commented publicly on the case.  

Goodrich, who was fired in September 2010, pled guilty to felony theft charges, according to Seattle PI. Seattle Police claim Goodrich's thefts cost the management company $566,000, including investigative expenses. Goodrich, a 55-year-old resident of Novato, Calif., is also alleged to have admitted to admitted to owing his former employer hundreds of thousands of dollars.  

Goodrich pleaded guilty to six counts of first-degree theft. Prosecutors will likely ask that Goodrich be sentenced to six months in jail when he is sentenced in February. If Goodrich hasn't paid back the full amount he stole by then, though, prosecutors will request a 14-month prison sentence. Goodrich initially claimed to have cleared the "loans" with his supervisor but later repaid $55,000 to the company. Reviews conducted by the band's investigators are alleged to have shown Goodrich also charged $134,000 in purchases to the company credit card.

Goodrich is expected to return to King County Superior Court on Feb. 21 to be sentenced by Judge Laura Middaugh. He is not currently jailed.
