Norman police released the 911 calls made in the moments after an OU student was killed at an off-campus apartment.
During the calls, witnesses could be heard describing the suspects and the suspects' SUV.
Police arrested 20-year-old Tyrek Ladarius Turner, 19-year-old Armani Ashanti Morgan, and two 17-year-old males in connection with the murder of 20-year-old Nathaniel Ewing.
The suspects were allegedly trying to rob Ewing and another individual. During the robbery, two shots were fired at the victims.
Ewing was shot in the abdomen.
His friends, as well as strangers from the nearby apartments, stayed by his side until first responders arrived to the scene.
In calls to 911, they told dispatchers that Ewing was conscious in the parking lot of the Willow Brook Apartments
Dispatcher: Are you with the victim?
Caller: Yes, I am. We need paramedics as soon as possible.
The dispatcher no more than asked the caller to monitor Ewing's pulse when the suspects apparently tried to double back to the scene
Caller: It's here, It's here.
Dispatcher: What's there, sir? What do you see?
Caller: It is the car that done the shooting.
Caller: They are turning around, they are coming back to the apartments.
Caller: Everybody back inside, everybody inside.
The caller stayed by Ewing's side and provided a detailed description of the suspects' SUV.
By Wednesday afternoon, Norman police announced they successfully executed search warrants and arrest warrants for Turner, Morgan, and two unidentified teenagers.
