A Salisbury Township man is heading to court on charges stemming from his 4-year-old's son death after he turned on a feed mixer without realizing his son was inside.

Alvin F. Beiler, 41, was scheduled for a preliminary hearing on Monday.

Court documents indicate Beiler's charges of involuntary manslaughter and endangering the welfare of children have been waived to court.

Police were dispatched on May 30 to a farm in the 500 block of Cambridge Road, where the boy was submerged in feed in a mixer. A deputy coroner pronounced the boy dead at the scene.

Beiler told police the boy was with him earlier in the evening, and that he allowed the boy to climb a silo as he worked the feed into the mixer.

Beiler then told officials the boy "disappeared" after climbing into the silo, according to police.

Beiler then turned on the machine, but stopped it after realizing the boy was inside. Police said Beiler then ran to a neighbor's house for help.

Beiler is scheduled for formal arraignment in Lancaster County Court on Nov. 21. He remains free on $100,000 unsecured bail/
