On the afternoon of Monday, January 7, 2019 a caller repeatedly called 911 stating he wanted to talk to an MCSO deputy at the MCSO Fountain Hills Substation located at 16705 E. Ave. of the Fountains, Fountain Hills, Arizona. At approximately 5:35pm an MCSO Sergeant went outside to the substation parking lot and contacted the subject, later identified as an 18-year old Ismail Hamed from Fountain Hills. The male subject began throwing rocks at Sergeant. The suspect then brandished a knife and advanced towards the Sergeant, despite his repeated commands for him to drop the weapon. The Sergeant discharged his service weapon which incapacitated the suspect. First aid was rendered on scene and the suspect was transported to the hospital and then booked into jail the next day.
