Prosecutors want to call the woman, Brittany Acoff-Howard, to testify at Balfour's upcoming trial but believe she may be hostile to the prosecution. They asked Judge Charles Burns to send a certificate to Berkeley County, South Carolina, where she now lives, naming her as a material witness. On Friday, Burns signed the certificate stating Acoff-Howard had failed a polygraph examination last December.
Balfour, 30, is scheduled to go on trial next month in the slayings of Jennifer Hudson's mother, Darnell Donerson, 57; brother,
Balfour was arrested on the day of the murders at the West Side home of another girlfriend who is also expected to be called to the witness stand by the prosecution.
Records show Acoff-Howard, 21, lived on the same block on South Yale Avenue as Hudson's family at the time of the slayings.
