Rejecting Evan Greebel’s defense that he fell victim to “master manipulator” Martin Shkreli, a high-profile former pharmaceutical executive that once controlled a former client, a federal judge sentenced the former Big Law partner to 18 months in prison Friday.

In a hearing that stretched more than three-and-a-half hours, U.S. District Judge Kiyo Matsumoto of the Eastern District of New York said that Greebel, who was a partner at Katten Muchin Rosenman when he represented Shkreli’s pharmaceutical company Retrophin Inc., was an experienced and “highly intelligent” attorney who knew what he was getting into when he served as an adviser to Shkreli and his business interests.
