MIDLAND CITY, Ala. (AP) — Authorities say they will be making a major announcement in the case of a 5-year-old who is being held hostage in an underground bunker in Alabama.

The news conference will be held Monday afternoon in Midland City. Police say 65-year-old Jim Dykes has been holding the boy hostage for days.

Before the news conference Monday, an ambulance that had been parked near the scene could be seen driving away. However, it was not clear if anyone was inside, and the vehicle did not have its sirens or emergency lights on.
