DUMAS, Ark. (NewsNation) — Arkansas State Police arrested a man in connection with a shooting at a car show that killed one and wounded 27 others.

Brandon Deandra Knight, 22, of Jacksonville, Arkansas, was arrested in connection with the shooting, that happened in Dumas on Saturday, Arkansas State Police announced in a news release.

Knight was taken into custody as he was being released from a Dumas hospital at 9:40 a.m. Wednesday.

He is charged with first-degree battery and aggravated assault, police said.

The victim who died was identified by authorities as 23-year-old Cameron Schaffer from Jacksonville. Six of those wounded were children, ranging in ranges from 19 months old to 11 years old.

Officials said what happened Saturday was the largest mass shooting incident in state history.

The car show where the shooting occurred is part of a community event held each spring. Called Hood-Nic, the foundation behind it says on its website that its mission is to “rebuild, reunite and respond to the needs of the youth in our communities.”

Knight is being held at the Dumas City Jail and has a court hearing scheduled for Thursday.

“The state police investigation remains in an active status and no further information regarding the arrest is available at this hour,” police said.

Investigators said earlier they believe the shooting started as an argument that escalated into two individuals getting in a gunfight.

NewsNation local affiliate KARK said victims of the shooting have been sharing their stories, including a woman who said she was trying to help a young girl who fell in the chaos when she herself was shot.
