The fiancee of former New England Patriots player Aaron Hernandez is set to ask a judge to throw out allegations that she lied to a grand jury.

Shayanna Jenkins is scheduled to appear before a Fall River Superior Court judge on Friday to seek dismissal of perjury charges against her. Prosecutors say she lied to a grand jury nearly 30 times during the investigation into the 2013 killing of Odin Lloyd, who was dating her sister.

Hernandez is charged with killing Lloyd. He's also separately charged with killing two men in Boston in 2012.

Jenkins' lawyers have argued in court papers that prosecutors set out to deliberately charge her with perjury, and that they failed to provide sufficient evidence to the grand jury.

Jenkins has pleaded not guilty.
