When does August decide to go look for May? What happened to her?

May assures everyone that she will be fine, but she goes out to the wall. August offers to accompany her, but May insists that she must go alone.After twenty minutes, May has not returned, so everyone goes out to find her. They search the wall and call her name in vain. August instructs June to call the police, pray to Mary, and then return. August and Lily begin to walk the river. Lily recites Hail Marys in her head and unintentionally aloud as they look for May. They find May’s flashlight on the ground, and soon they find May’s body in the river with a stone on top of her. August does her best to revive her sister, but she soon announces that May is dead.
