Quote from Magna:
The defense medical examiner's supposition was wrong. When Chante Mallard testified at the sentencing hearing (she didn't testify during the actual trial) she described exactly what happened. She said Gregory Biggs (the man she struck and left embedded in her windshield to die) was moaning while her car was parked in her garage when she returned home. Hard to argue with her since she was the only one there who is still alive, and equally hard to make a case for leniency.
I stand corrected.
