On May 22, 2015, prosecutors dropped their opposition to a new trial. This came largely due to defense claims that the prosecution's star witness, Armando Morales, had perjured himself on the stand. The defense contended that prosecutors failed to disclose that Morales was a jailhouse informant with a reputation for being untrustworthy. Morales had denied ever being an informant. The defense also argued that Morales made up Guandique's confession in order to boost his stock with prosecutors. On June 3, 2015, the defense said that a new witness, a neighbor, called 911 at 4:37 a.m. on the last day Levy was alive in order to report hearing a 'blood-curdling scream', possibly coming from Levy's apartment. On June 4, 2015, Judge Gerald Fisher granted a motion for the new trial. On June 12, 2015, Judge Robert E. Morin set the retrial of Guandique for March 1, 2016 but in March, the trial date was moved to October 11, 2016.
