An authenticated video surfaced on the Internet that shows two gunmen and a police officer, Ahmed Merabet, who is wounded and lying on a sidewalk after an exchange of gunfire.
This took place near the corner of Boulevard Richard-Lenoir and Rue Moufle, 180 metres (590 ft) east of the main crime scene.
One of the gunmen ran towards the policeman and shouted, "Did you want to kill us?"
The policeman answered, "No, it's fine, boss", and raised his hand toward the gunman, who then executed the policeman with a fatal shot to the head at close range.

Sam Kiley, of Sky News, concluded from the video that the two gunmen were "military professionals" who likely had "combat experience", saying that the gunmen were exercising infantry tactics such as moving in "mutual support" and were firing aimed, single-round shots at the police officer.
He also stated that they were using military gestures and were "familiar with their weapons" and fired "carefully aimed shots, with tight groupings".

The gunmen then left the scene, shouting (according to witnesses), "We have avenged the Prophet Muhammad.
We have killed Charlie Hebdo!"
They escaped in a getaway car, and drove to Porte de Pantin, hijacking another car and forcing its driver out.
As they drove away, they ran over a pedestrian and shot at responding police officers.

It was initially believed that there were three suspects.
One identified suspect turned himself in at a Charleville-Mézières police station.
Seven of the Kouachi brothers' friends and family were taken into custody.
Jihadist flags and Molotov cocktails were found in an abandoned getaway car, a black Citroën C3.
