He has first- and second-degree burns and a lung infection, according to his mother and friends.
Authorities announced a juvenile had been charged with first-degree arson “as the individual responsible for causing the victim’s severe burns,” according to a statment from Kerrville Fire Marshal Chris Lee.
No age or identification was given for the juvenile.
The incident occurred when Kayden was out riding his bike and didn’t come home for lunch, family friend Donya Young told InsideEdition.com Wednesday.
His mother, Trysten, got a text message saying her son had been burned and telling her where to find him, Young said. As the mother arrived, the boy was being loaded into an ambulance.
The boy was alone when firefighters arrived. They were called to the scene on a report of a shed on fire, according to Kaitlyn Berry, spokeswoman for the city of Kerrville.
