Aaron Hernandez's cousin, Tanya Cummings-Singleton, has been jailed for refusing to testify in front of a grand jury investigating the former football star's murder case, the Hartford Courant reported Thursday.
Cummings-Singleton, 37, who lives in Bristol, Conn., was determined to be in contempt when she was subpoenaed to appear but declined. She has been held at the South Bay House of Correction in Suffolk County since Aug. 1, the newspaper reported.
Cummings-Singleton will remain incarcerated at the discretion of a judge.
Last month, prosecutors said Cummings-Singleton used a credit card in a former name to purchase a get-away bus ticket for Ernest Wallace, a defendant in the June 17 killing of Odin Lloyd, a 27-year-old semipro football player and Hernandez's friend.
Prosecutors made the allegations at Wallace's bail hearing.
Wallace -- who has pleaded not guilty to being an accessory after the fact and is being held on $500,000 bail -- took a bus from Georgia to his parents' house in Miramar, Fla., prosecutors said. When he realized he was the subject of a nationwide manhunt, Wallace surrendered to Miramar police.
Prosecutors said police seized Cummings-Singleton's credit cards and cell phone.
Police, however, have not found a cell phone used by Wallace on the night of the shooting, prosecutors said. That phone was registered to Cummings-Singleton, they said.
Hernandez -- who "orchestrated" the killing, according to prosecutors -- has pleaded not guilty to murder and is being held without bail.
Cummings-Singleton had been staying at the Bristol home of Hernandez's uncle, where police arrested defendant Carlos Ortiz in the days after the shooting. Police also have searched the house several times, plucking from the garage a folder and an SUV, rented in Hernandez's name, that had been sought in connection to a 2012 double homicide in Boston.
Police also wanted to question Cummings-Singleton's husband, Thaddeus Singleton III, before he died in a car crash in Farmington, Conn., in June.
Ortiz, charged with illegal possession of a firearm in connection with the shooting, said in his last probation visit before the shooting, that he was staying with Cummings-Singleton. According to court documents, he told investigators he discussed the shooting with Cummings-Singleton before he was arrested.
Court documents have revealed that Ortiz told investigators that Wallace said Hernandez is the shooter.
Grand jury proceedings are secret and prosecutors have not revealed who has testified, but court records have revealed two: Alexander Bradley, a Connecticut man ordered by a judge to testify after he filed a lawsuit in Florida alleging Hernandez shot him in the eye in February, and Jose Olivares, who helped police locate an apartment Hernandez rented for Wallace in Franklin, Mass.
Prosecutors said police found ammunition in the apartment that matched the caliber used in the Lloyd shooting.
For several days, divers have searched a lake approximately two miles from Cummings-Singleton's home, looking for the murder weapon.
