Little Murders:From Defenders and Offenders:
This fiend murdered his two grandsons at his farm, at a place called Annville, in Pennsylvania. The old man fell in love with Mrs. Sergeant, of some 45 summers, but she refused to become mistress of his farm until the two lads were put away in some orphan asylum. Instead of doing this, he strangled the two lads, with devilish deliberation, burned their clothes and buried their bodies in a ditch near his home; but fortunately the crime was discovered a few days afterwards and his arrest followed.
