Never-before-seen video of Officer Darren Wilson on the night he shot unarmed 18-year-old Michael Brown in Ferguson, Mo., contradict police testimony, according to Brown’s family.

The video shows Wilson leave for the hospital a few hours after he shot Brown fatally, an incident that sparked weeks of protests and at times violent clashes with heavily armed police. It also started a nationwide discussion on the treatment of black people by the police.

The police department leaked information that Wilson had been severely beaten and suffered an orbital eye socket “blowout,” which suggested that the shooting was justified, but the video released indicated the “initial description of his injuries were exaggerated,” according to a statement from Brown’s family as quoted by ABC News.

Wilson claimed that he shot Brown in self-defense after Brown tried to grab at his gun and they wrestled in the police car. Brown’s family and some eyewitnesses claim that Wilson shot him after he already surrendered.

The video shows the 28-year-old Wilson leave the police station without assistant along with another officer and a police union lawyer two hours after the shooting.

In what could be a key piece of evidence, audio tapes do not show Wilson making a connection between Brown and a convenience store robbery that police say Brown was involved in earlier.

Dispatch calls obtained by the St. Louis Post-Dispatch indicated that Wilson asked other units if they needed help locating a robbery suspect. A few minutes later, an officer asked for help controlling the scene where Brown would eventually be shot. The officer said more units were needed as “there’s going to be a problem.”

Brown was ultimately shot six times by Wilson, which sparked weeks of protests and even incidents of looting within the outraged community of Ferguson, which is near St. Louis.

Wilson has since been suspended with pay and has stayed in hiding. A state grand jury is examining whether to press criminal charges against Wilson, with a decision expected sometime this month.
