Five people wounded in a late-night shooting at a teenage birthday celebration in rural Alabama remained in a critical condition early on Monday, hospital authorities said.
Four people died and a further 28 people were wounded in Saturday's shooting at the Mahogany Masterpiece Dance Studio in Dadeville, a community of 3,200 people.
All four who were killed were high school seniors, and of the nine wounded still in hospital, five were in critical condition, a spokesperson for Lake Martin Community Hospital told a news conference.
Authorities have not said whether any suspect in the shooting had died or been arrested.
