A Chicago man who admitted shooting dead seven people and wounding dozens of others during a 2022 Independence Day parade has been sentenced to life in prison without the possibility of parole.

Shootings and other violence during the extended July 4 weekend have left at least 33 people dead across the US, including 11 in Chicago, and injured dozens more nationwide, authorities said.

The man accused of killing seven people at a 2022 Independence Day parade in Chicago has rejected a deal requiring him to plead guilty to seven charges of murder in a stunning courtroom scene just days before the second anniversary of the attack.
