Nolan later took to social media to describe the terrifying encounter, writing on Facebook, 'Andrea just attempted murder on me... tried shooting me in the face and tried shooting my friend in the car.'

Whilst Nolan managed to escape the gunfire completely uninjured, a female bystander standing near the vehicle was caught in the crossfire.

Arriving officers discovered that the woman had been shot in the back of the head. She was immediately rushed to a local hospital where medical staff confirmed that, despite the severity of the injury, she is expected to survive.

The situation escalated rapidly into a hostage crisis as Davis fled back toward the family residence in northwest Phoenix. While Glendale police officers were still processing the active crime scene at the sports bar, Nolan began receiving a series of deeply disturbing text messages from his wife.

Davis told him that she intended to inflict severe harm upon their two children. The emergency response turned frantic when the suspect sent a final text message containing a photograph of one of the children bleeding heavily from the head.

Armed with this critical information, officers from both the Glendale and Phoenix police departments converged on the property, located near 51st Avenue and Bell Road.
