Adam Klein—the last of the students arrested in Operation Ivy League to begin pretrial proceedings—was denied diversion to treatment in a Manhattan courtroom today, reports Bloomberg. Had he been granted diversion and completed the program successfully, Klein could have avoided a felony charge on his criminal record.

“Obviously we’re disappointed,” Klein’s attorney, Alan Abramson, told Bloomberg. “We think Adam is an ideal candidate for diversion and the kind of defendant the diversion statute was created for.”

Klein now faces a sentence of 2 and a half years (maximum) if he’s convicted of criminal sale of a controlled substance.  He, along with the other defendants, was offered a plea bargain in June, turned it down.

Klein and Stephen Perez, also known as “Stephan Vincenzo,” are the only two Operation Ivy League defendants whose cases are still ongoing. Harrison David was convicted of a felony drug charge in August and received a few months in jail, while Michael Wymbs pleaded guilty last month and received five years of probation. Christopher Coles was more fortunate, as Judge Sonberg granted him a diversion to treatment a few weeks ago.

Perez has a court hearing scheduled next Tuesday, and Klein will return to court Jan. 10.
