On CNN’s Larry King Live Thursday, comedian Dane Cook confessed that he felt a sense of “terrible betrayal” after he learned his half brother was suspected of embezzling millions of dollars from him.

Last December, Darryl McCauley, 43, was arraigned in Massachusetts on charges of embezzling approximately $10 million from his entertainer brother. Prosecutors allege that McCauley stole the money from Cook while being paid $12,500 a month to act as Cook’s business manager as part of his company, Great Dane Enterprises, Inc.

“I worked with my only half brother for several years,” Cook said. “Woke up one day and a lot of stuff was missing. There is a good chunk of money that is certainly not accounted for. That’s all I can say about it at this point.”

Darryl has pleaded not guilty and is currently in jail awaiting trial.
