At least nine people were injured, including juveniles, early Sunday in a shooting at a large birthday party at an Airbnb rental house in a suburb of Akron, Ohio, according to police.

“I think he’s dead. There’s blood everywhere!” one caller shouted at a 911 dispatcher, as screaming in the background can be heard.

Authorities say the victims suffered gunshot wounds and other injuries when gunfire erupted at a party that was advertised on social media.
