The 2nd woman was captured by a surveillance camera walking into Nordstrom's with the prime suspect right after Saturday's attack.
Tonya Knight-Joseph's finger was bitten and nearly severed during a dispute over a parking space, police say.
Knight-Joseph also suffered scratches to her face. She was released from Cooper University Hospital Monday afternoon.
Doctors say it will be a week before they know if Knight-Joseph's finger will have to be amputated.
The suspect who Knight-Joseph says bit her is described as a black female in her mid-30s with a heavy set build and "bushy" hair.
The 2nd woman being sought by police is described as a thin black female who was wearing a light colored shirt, dark jacket and sunglasses.
Anyone with information about the case or either suspect is asked to call the Cherry Hill Police Department at (856) 488-7828.
