Authorities say no charges will be filed in the death of a 4-year-old boy who was struck and killed by a piece of farm equipment in eastern Pennsylvania.
    
Investigators have determined that MichaelLyn Wenger's death was an accident.
    
The child was struck by a manure spreader around 9:15 a.m. Saturday at a farm in Maxatawny. Authorities say the child lived in the town, but haven't said why he was at the farm.
    
The boy was taken to a hospital but was pronounced dead there shortly after 10 a.m. The cause of death was blunt-force trauma.
    
No other injuries were reported in the accident.
