A source told KPNX the driver’s name is Misty Lee Wilke – and she had just found out the man had HIV.
She also claimed he had pulled a knife on her and cut her arm, so she jumped into her car and drove without looking.
He reportedly sustained a severe head injury and a broken back, but survived.
A Maricopa County grand jury indicted Wilke on charges including attempting to commit second-degree murder, leaving the scene and aggravated assault with a deadly weapon.
Wilke is pleading not guilty to the charges
