Shemar Moore was in a Los Angeles court yesterday to testify against his former Criminal Minds co-star, Keith Tisdell. Moore claims that Tisdell owes him approximately $60,000 and demands that his former colleague and friend repay him. The two first became close after they met on the hit CBS show back on season two of Criminal Minds. Moore started a charity organization to help those who battle Multiple Sclerosis, a disease that plagued his mother.
