Agency director Col. Frank Milstead told The Arizona Republic that King had significant injuries when he was hospitalized after Wednesday night's shooting and was put in a medically induced coma.
Milstead says King, who has a history of mental illness, had initially refused treatment.
He did not detail his injuries. Milstead says doctors treated him anyway for fear "he would not survive."
Official police documents show that King is mentally disturbed and was also under the influence of drugs or alcohol at the time of the incident.
Authorities say King fatally shot Trooper Tyler Edenhofer while fighting officers along Interstate 10 in Avondale.
Isaac King is facing multiple charges including first-degree murder, two counts of attempted first-degree murder, two counts aggravated assault, three counts endangerment, and resisting arrest.
