Burger King on 40th and Pulaski in Chicago

*In May, the district manager of a Burger King restaurant in Chicago said police officers deleted footage from one of their security cameras located fewer than 100 yards from where 17-year old Laquan McDonald was shot and killed.

On Tuesday, Cook County State’s Attorney Anita Alvarez addressed the missing footage, saying it has undergone forensic testing to determine whether or not it was “tampered with.”

“Forensic testing was done on the Burger King surveillance system to determine if anyone tampered with the evidence and the testing did not reveal any such evidence,” she said.

McDonald was shot 16 times by a Chicago police officer on the night of October 20, 2014. Nine of the shots struck McDonald in the back, according to the Medical Examiners report. First degree murder charges were filed Tuesday against Officer Jason Van Dyke .

On the night of the shooting, McDonald was trailed by Chicago police officers through the Burger King parking lot on 40th and Pulaski after a call about a man with a knife, according to attorneys for the McDonald family. The 86-minutes of missing video runs from 9:13 p.m. to 10:39 p.m., according to the lawyers for McDonald’s family. He was shot at approximately 9:50 p.m.

Just south of the restaurant, McDonald was shot after police on the scene said he posed a “very serious threat” to the officer’s safety. But that claim is disputed by attorneys for McDonald’s family and by some eyewitnesses that night.

According to Burger King District Manager Jay Darshane, four to five police officers wearing blue and white shirts entered the restaurant after the shooting and asked to view the video and were given the password to the equipment. Three hours later they left, he said.

The next day, when an investigator from the Independent Police Review Authority [IPRA] asked to view the security footage, it was discovered that the 86 minutes of video was missing.

In a statement, a spokesman for the IPRA said: “We have no credible evidence at this time that would cause us to believe CPD purged or erased any surveillance video.” But according to Darshane, both the cameras and video recorder were all on and working properly the night of the shooting. He believes one of the detectives deleted the files.

“We had no idea they were going to sit there and delete files,” Darshane said. “I mean we were just trying to help the police officers.”
