Chicago- It is a video that has taken over a year to be released. A white Chicago police officer shooting and killing a black teenager. That teen, seventeen-year-old Laquan McDonald was shot 16 times by police officer Jason Van Dyke, who emptied his gun and prepared to reload.

This is the dashcam video of that shooting which was only released because of a court order.

Tuesday, for the first time in 35 years, a Chicago police officer was charged with first-degree murder. Officer Van Dyke was also denied bond by the judge.

Van Dyke has had 20 misconduct complaints made against him during the past 4-1/2 years, none of which led to any discipline from the Chicago Police Department.

McDonald was reportedly holding a knife with a three-inch blade when police spotted him and pulled over. McDonald was on foot at the time. Officer Van Dyke was not among the first officers to attend.

There were no words spoken by McDonald during the incident. He said nothing in response to numerous verbal commands to drop the knife, police said.

The first responding officer said he did not see the need to use force.

But an officer armed with a Taser was requested to attend and deal with the situation but none arrived.

Officer Van Dyke, who arrived in a patrol car with a partner, was at the scene for less than 30 seconds before he started shooting. He was out of his car for approximately six seconds before he opened fire.

Officer Van Dyke shot the teenager 16 times. The 16 fired cartridge cases police recovered at the scene were all from his weapon.

McDonald was lying on the ground for 13 of these seconds as the shots were fired. Officer Van Dyke was preparing to reload when his partner, who could hear McDonald struggling to breathe, told him to hold his fire.

The prosecutor said the teenager still had a pulse when paramedics arrived but was declared dead at the hospital.
