CHICAGO - A white police officer charged with murder in the 2014 fatal shooting of black teenager Laquan McDonald pleaded not guilty Tuesday.

Jason Van Dyke is "hanging in there" and wants to tell his side of what happened so he's not seen "as this cold-blooded killer," defense attorney Dan Herbert said after the court hearing. Herbert added that they haven't ruled out asking for a change of venue. The case is in Cook County Criminal Court in Chicago, where demonstrators have staged marches protesting the shooting and how it's been handled.

Van Dyke, 37, faces six counts of first-degree murder and one of official misconduct in the death of 17-year-old McDonald. The officer, wearing a dark suit and blue striped tie, appeared in court Tuesday as his lawyer entered the plea on his behalf.

Judge Vincent Gaughan set the next hearing for Jan. 29.

Public outcry has been furious since a dashcam video was released last month showing the veteran officer shooting McDonald 16 times.
