Mark Epstein, the brother of disgraced financier and convicted sex criminal Jeffrey Epstein, abruptly ended an interview on Monday after he was asked about the victims of his brother's crimes. Epstein joined journalist Piers Morgan on his eponymous YouTube show, where he was asked about the latest release of files from the FBI's investigation into his brother. Epstein claimed the files added credence to his theory that Jeffrey was murdered while in jail. He also claimed that the FBI has been playing "games" to portray his brother's death as a suicide. But the interview took on a decidedly different tone when Morgan asked Mark Epstein about the victims of his brother's crimes. "I didn’t know what he was up to. A lot of the stuff that’s come out has surprised me. I wasn’t aware of this stuff … that was his problem …" Mark Epstein said. "Again, unfortunately, I really don’t care, to be honest with you." “But you care about the victims, I presume, of your brother?" Piers asked.“These are the questions I don’t get into. Have a nice day!” Epstein said, abruptly hanging up.“Ok, extraordinary, not a difficult question to answer,“ Piers said.
