Shayanna Jenkins has sat faithfully with the family of her fiancée, Aaron Hernandez, during her occasional courtroom appearances for his murder trial.
She's chatted with his mother and uncles. She's held Hernandez's brother's hand for support.
She's smiled at the former New England Patriots star, the father of her 2-year-old daughter, as he's entered the fifth floor of Bristol County (Mass.) Courthouse, even though he's accused of killing the boyfriend of her own sister.
Now the whole thing could flip.
On Tuesday, Judge E. Susan Garsh endorsed an application to grant Jenkins immunity in exchange for her testimony.
