Chicago Cop Pleads Not Guilty to Killing Teen

A Chicago Police officer who shot a teen 16 times has pleaded not guilty to murder charges. 

Jason Van Dyke appeared in Cook County criminal court Tuesday. 

Van Dyke has been charged with six counts of murder for the shooting death of 17-year-old Laquan McDonald in 2014. 

Van Dyke posted 10 percent of his $1.5 million bail last month and was released from jail. 

Authorities released dash-cam video of the shooting in November. 

The video shows McDonald walking in the middle of the street while holding what appears to be a knife. 

Van Dyke opened fire six seconds after getting out of his squad. 

He fired 16 rounds at McDonald and was reloading when another officer told him to hold fire. 

Van Dyke kept shooting, even after the teen fell to the ground. 

The video led to weeks of protests and to the forced resignation of the Chicago’s police superintendent.  

Van Dyke’s attorneys say they haven’t ruled out asking for a change of venue. 

A federal investigation has been launched into the Chicago Police Department’s practices.
