Shayanna Jenkins is scheduled for a 9 a.m. hearing Friday in Superior Court in Fall River.
Prosecutors filed a motion to dismiss the perjury case Thursday, citing Jenkins' testimony against Hernandez in March. The former Patriots tight end was convicted and sentenced to life in prison last month in the killing of Odin Lloyd, who was dating Jenkins' sister.
Jenkins had pleaded not guilty to perjury for allegedly lying to the grand jury that investigated Lloyd's death. She was granted immunity by the court in February, which compelled her to testify at Hernandez's trial.
