Flagstaff police were searching for an Ash Fork man accused of threatening a mass shooting on Friday.

On Saturday, Flagstaff police announced an arrest warrant for 36-year-old Justin Wayne Hill, who was identified as the suspect behind numerous mass shooting threats outside various schools, businesses and government offices in the Flagstaff area.

Hill is said to have spread his messages online and on the social platform Yelp and to have contained “threats related to mass shootings,” said Flagstaff Police Sergeant Jerry Rintala.

According to Rintala, police were searching intensively for Hill on Saturday afternoon.

Hill was described, according to Rintala, as a white man, approximately 6 feet tall, of medium build, with brown hair and blue eyes.

According to Rintala, Hill was probably driving a blue 2009 Subaru Impreza with Arizona license plate CKA72E.
