Woman charged in bus murder had history of violence

A 29-year-old Detroit woman is charged with murder for a deadly stabbing on a Detroit bus Wednesday afternoon.

The suspect, Tiffanie Monique Edwards, has a long history of violence and a rap sheet to match.

Edwards was friendly to a Detroit judge Friday morning, as she was formally charged with murder in the first degree

"Good morning," she said.

A video filmed by a witness showed the aftermath of the fatal stabbing she is accused of, on a Detroit Department of Transportation bus near Henry Ford Hospital. Edwards allegedly stabbed 50-year-old Charla Williams in the face and body, sometime after she was bumped with her walker.

Court records show Edwards has history of violent crimes including the assault and injury of a police officer in 2011.   In the spring of 2011 Edwards was charged with felonious assault and battery with a dangerous weapon. She pleaded no contest, but before she could be sentenced she was charged with assaulting a police officer and resisting arrest.

She was sentenced to two years probation and community service at that time.

Edwards is likely to face a much different sentence this time around. If convicted on her charges of first degree murder as a habitual offender, she would face life in prison.
