Massachusetts State Police last week arrested the half-brother of Dane Cook for embezzling more than $10 million from the popular comedian. Prosecutors said Darryl McCauley illegally wrote himself checks of up to $3 million while working as Cook’s business manager, spending the money on cars and vacations. A search of McCauley’s house turned up $800,000 in a wall safe. McCauley’s lawyer denied the charges, saying, “McCauley has been critical to Mr. Cook’s success.”
