-- Newly released dash cam footage shows the moment that officers arrested accused Charleston mass murderer Dylann Roof -- high-fiving and fist-bumping each other after placing the suspect in a police car.
According to the arrest report, police found a semi-automatic handgun hidden beneath a pillow in the backseat of the car Roof was driving, and pulled him over because he was driving too close to a tractor-trailer.
The audio recording of the 911 call that alerted police to Roof was also released. The owner of a flower shop is heard telling officers that one of his drivers believed that she was behind the suspected shooter, and relayed that message to her boss.
The video shows two officers approaching Roof's car, one with his gun drawn. The other is seen putting his gun back in his holster as he approaches the driver's side window.
Roof is frisked by one of the officers once he gets out of the car, then is put in handcuffs while facing his vehicle.
More officers approach his black Hyundai Elantra as another officer walks the 21-year-old over to one of the at least three police vehicles on the scene.
One of the dash cam recordings captures the remaining officer's brief moment of celebration once Roof is securely in the police vehicle.
The arrest took place about 240 miles north of Emanuel AME Church, where the shooting took place around 9 p.m. on June 17.
The police report states that a Glock semi-automatic handgun was found in the backseat of the Hyundai Elantra that Roof was driving. It is unclear if it was the same weapon he allegedly used during the church shooting.
These are the first official recordings to be released of Roof's arrest. He has since been charged with nine counts of murder and one weapons related charge and is being held in a Charleston jail. He has not yet had to enter a plea.
