A man accused of driving his vehicle into a traditional Christmas parade near Milwaukee late last year, killing six people and injuring dozens others, pleaded not guilty on Friday to multiple criminal charges.

Darrell Brooks, 39, entered the pleas to 77 charges, including six counts of homicide and several counts of reckless endangerment, in a court appearance.

“Not guilty plea entered. Bail remains as fixed,” court records showed after Friday’s proceedings.
