Boy, 4, Dies in Manure Pit

(Lancaster, Pennsylvania) A 4-year-old boy, Josiah Martin, was found dead Saturday morning, face down in a manure pit.

Police say Josiah Martin was playing with two siblings and a neighbor child Saturday morning on the farm just outside New Holland when he wandered off.

Reportedly, the manure pit has a chain-link fence surrounding it. Excuse me for being inquisitive but, what good is a fence if it can't keep a 4-year-old boy out?

Also, why is a 4-year-old ever allowed to "wander off" from adult supervision?
