From the item below (about a third of the way down the page):
At bond court, prosecutors said Van Dyke opened fire six seconds after exiting his squad car as McDonald was walking away from him at 41st Street and Pulaski Road.
Van Dyke then fired 16 rounds at McDonald in about 14 seconds and was reloading when another officer told him to hold his fire, prosecutors said at bond court.
