Local officials gave few details about the incident at their initial press conference besides confirming the shooting unfolded at a birthday party.  

"This morning, our nation is once again grieving for at least four Americans tragically killed at a teen’s birthday party in Dadeville, Alabama as well as two others killed last night in a crowded public park in Louisville," President Biden said in a statement on Sunday. "Jill and I are praying for their families, and for the many others injured and fighting for their lives in the wake of this weekend’s gun violence.

"What has our nation come to when children cannot attend a birthday party without fear? When parents have to worry every time their kids walk out the door to school, to the movie theater, or to the park," the president added.

Biden said guns are the leading killer of children in the U.S., calling it "outrageous and unacceptable."

He also said he stands ready to work across the aisle "in good faith" on legislation surrounding gun laws that "will save lives." 

Local representatives also weighed in on the tragic incident.

"This morning, I grieve with the people of Dadeville and my fellow Alabamians. Violent crime has NO place in our state, and we are staying closely updated by law enforcement as details emerge," Alabama Gov. Kay Ivey, a Republican, tweeted Sunday morning.

She confirmed to Fox News the hospital treated multiple victims and released them. Several victims with gunshot wounds have had to be transferred to other hospitals to better tend to their specific wounds/injuries. Of the victims treated at the medical center, she had no word on any fatalities. Foy would not get into ages of victims or a specific number. The hospital is a small, rural facility with just 81 beds. It’s not rare to transfer patients to other facilities that have access to more specialists.
