The manager of a downtown Chicago Burger King testified in court recently that there was an unexplained 86 minute gap in the surveillance video he had turned over to Chicago police. The Burger King is located several yards from where the shooting of Laquan McDonald, 17, took place last year.

Burger King manager Jake Darshane has accused the Chicago police department of erasing 86 minutes of surveillance video that may have captured the shooting. McDonald, a black teenager, was shot 16 times last year by white Chicago police officer Jason Vandyke. Vandyke had since been put on administrative assignment, reports The New York Times.

Vandyke has been charged with first-degree murder, and the shooting has sparked days of violent protest in downtown Chicago. The FBI has seized the Burger King surveillance video for examination. Earlier last week, the police car dash cam video was released to the public showing the shooting of McDonald. It was the release of this video that has set off the demonstrations these last few days.

It is not clear what the Burger King tapes may have shown but according to Darshane the 86-minute gap occurs at the time of the shooting. The dash cam tape was released on Tuesday of last week but police only released it on a judge’s order. Darshane’s insinuation that the police erased portions of the surveillance video has only added to the roar that the police have mishandled this investigation and that there was a cover up going on with regard to what had actually happened.

Darshane testified that the police were at his restaurant in only a few minutes following the shooting and demanded that they have immediate access to the surveillance footage. Darshane said that the police stayed for two hours and then left. It was then that Darshane noticed the 86-minute erasure in the tape.

Darshane commented that he was just trying to help the police when he turned over the tape. “I didn’t know they were going to delete it,” he said.
