A man accused of ramming a car into Christmas parade-goers in Wisconsin on Sunday is to be charged with six deaths after another victim - a child - died, APA reports citing BBC.
Darrell Brooks, 39, wept as he was arraigned in court with five counts of intentional homicide. Prosecutors said further charges would be filed.
Police say Brooks drove in a "zig-zag pattern" to hit as many people as possible at the Waukesha parade.

He had been marching with his baseball team when he was struck. A GoFundMe page said Jackson underwent brain surgery on Sunday and needed "a miracle".
His brother, who suffered a fractured skull, is expected by family members to recover. Tucker was among 62 people injured.
Police said 18 of the injured were children. Several victims remained in critical care in hospital.

"I have not seen anything like this in my very long career," Judge Costello said.
The other victims have been named as Virginia Sorenson, 79; LeAnna Owen, 71; Jane Kulich, 52; Wilhelm Hospel, 81; and Tamara Durand, 52.
A medical examiner has concluded they died of "multiple blunt force injuries", according to a criminal complaint released on Tuesday.
According to the complaint, Brooks ignored officers' attempts to make him leave the parade route before accelerating his vehicle into the crowd.
One officer said the driver looked like he "had no emotion on his face".
Police said the red Ford Escape SUV "appeared to be intentionally moving side to side" and witnesses felt this was "a direct intent to hit as many parade
