According to police, around 1 p.m., the woman, later identified as 26-year-old Chandler Cilk, was in driver's seat when, for unknown reasons, she fell onto the road and was hit by her truck. Paramedics found Cilk on the ground and took her to a nearby hospital, where she died. The pickup truck was found crashed into a fence.
"It is still unclear how she ended up on the roadway. That is the question that investigators are hoping to get answered," said Sgt. Ann Justus with the Phoenix Police Department.
A man at the scene was detained, but Justus later said that he wasn't involved. An investigation is underway.
