Aaron Hernandez's Cousin Pleads Not Guilty To Contempt In Double Murder Probe

BOSTON (CBS/AP) — A cousin of former New England Patriots player Aaron Hernandez pleaded not guilty Monday to a criminal contempt charge.

Tanya Singleton made a brief appearance for her arraignment in Suffolk Superior Court.

Prosecutors allege she refused to testify before a grand jury investigating Hernandez's role in a double slaying in Boston's South End even though she had been granted immunity.

Hernandez has pleaded not guilty to two counts of murder in connection with the July 2012 shootings of Daniel de Abreu and Safiro Furtado.

He has also pleaded not guilty in another fatal shooting in Bristol County.

Singleton's attorney, E. Peter Parker, has said his client is being treated for breast cancer and called her prosecution "aggressive and unnecessary."

Singleton was released to home confinement on GPS monitoring .

She's due back in court July 15.
