A 22-year-old woman who sliced the throat of a cab driver and left him bleeding on the road while she drove away will be sentenced Sept. 8 in Sarnia court.

Samantha Edwards of Sarnia pleaded guilty Wednesday to the July 28, 2014 charge of aggravated assault, theft of the cab and driving while disqualified.

Sentencing was adjourned until September to allow for the preparation of a pre-sentence report.

Court was told that on July 28 Edwards had requested a cab in downtown Sarnia and was driven to the area of Blackwell Road.

After asking the driver to stop, Edwards lunged at him, slicing his throat.

A struggle ensued outside the cab and Edwards got the keys from the driver.

During the struggle, Edwards destroyed the radio that the driver was trying to use to call for help.

The driver was bleeding on the roadside until a passerby called police and paramedics.

A short time later, Edwards stopped at a home where she asked to wash off from her body what she said was paint.

When she asked for another cab to be dispatched, police arrived to arrest her.

Police officers did not detect the impact of drugs or mental health issues and Edwards appeared to show no remorse.

The driver’s wounds required surgery.

Edwards acknowledged her guilt, said defence lawyer David Stoesser.

Stoesser said he would be presenting materials regarding Edwards’ mental health during the sentencing hearing.
