At least eight people were fatally shot and dozens were injured during parties or gatherings on or related to the Juneteenth holiday injured in seven parts of the country, according to officials and local reports. 

Shootings on Saturday – a newly declared federal holiday honoring Juneteenth – were reported during events in Colorado, California, Michigan, Pennsylvania, Indiana and South Carolina, among others, with at least 33 wounded, according to authorities and multiple reports. 

Speaking to reporters following multiple shootings in her city on Saturday, Philadelphia Police Commissioner Danielle Outlaw noted that many began the day celebrating the designation of Juneteenth as a new federal holiday commemorating the end of slavery but "we again found ourselves lamenting as an otherwise beautiful afternoon had been sullied with gun violence."

Parades, picnics and lessons in history were offered Saturday to commemorate Juneteenth in the U.S., just two days after Congress and President Joe Biden created a federal holiday to observe the end of slavery.

But the day was also marked with tragedy for some.
