According to witnesses, the victim and the suspect had been arguing earlier; and, as the victim was getting off the DDOT bus near Grand River and Rosa Parks, the victim “bumped into” the suspect with her walker. That’s when, witnessed said, younger woman pulled out a knife and started to repeatedly stab the older woman.

Edwards turned herself in Thursday after intense media coverage led to a tip to police.

A probable cause conference was scheduled for Friday, Sept. 4 and a preliminary hearing was set for Sept. 10.
