May 23, 1891 Mariposa Gazette: A Sad Accident.
One of the most depressing accidents which has happened here for a long time, occurred at the Malone mine, about six miles from Mariposa, last Saturday evening, near five o'clock. Mr. Frank Castagnetto and a Chinaman were engaged in stoping from the lower level, when a rock weighing about a ton, fell, crushing Mr. Castagnetto under it. His fellow workers hastened to him at once, but he never spoke, and life was extinct in less than five minutes from the time the rock fell. His body was taken at once to his home in Bear Valley, where his grief stricken wife and three little children awaited the sad home coming. The news also fell with cruel force on his aged parents and devoted brothers and sisters.
Mr. Castagnetto was born and raised in Bear Valley, and was loved and respected by a very large circle of friends, and his sudden and terrible death cast a gloom over the entire community. He was a son of Mr. and Mrs. Dominico Castagnetto of Hunter's Valley, who appeared almost unable to realize that the crushed, helpless form before them, was their handsome and beloved boy, Frank. People gathered from all parts of the county to pay last tribute of respect to his memory, and there were many tears shed as coffin was lowered from view. The sympathy of the community is with the bereaved family.
