AUSTELL, Ga. (AP) — Georgia officials ordered a popular roller coaster that hit and killed a teenager over the weekend to remain closed Monday.

Asia LeeShawn Ferguson IV of Columbia, S.C., died Saturday at Six Flags Over Georgia after police said he hopped two fences and wandered into a restricted area where he was decapitated by the Batman roller coaster. Police said an autopsy determined the teen's death was an accident. Toxicology tests could take several weeks.
