The Arizona Department of Corrections, Rehabilitation and Reentry took a month to submit a brutal inmate-on-staff assault case to prosecutors and did so the day after ABC15 let officials know the station obtained leaked video of the attack.

Police say an investigation is underway after a man was struck and killed by a car in Phoenix overnight on Sept. 4. According to officials, the incident happened in the area of 7th Avenue and Osborn, and the driver allegedly involved returned to the scene after the accident. Police say the driver did not know what he struck until he got home. #crash #phoenix #phoenixarizona #phoenixaz #arizona #az #news #us #usa #usa🇺🇸 #fox10 #fox10news #fox10phoenix
