A Lady Murderously Assaulted by a Chinaman
Mrs. Henry Schlosser, of San Quentin Probably Murdered
A horrid and unexplainable crime was committed at San Quentin yesterday morning, by a Chinese convict domestic, in the house of Mr. Henry Schlosser, the foreman of the furniture works at the prison. Mrs. Schlosser is an invalid, and it is her husband’s custom to take his breakfast before she gets up. He had taken his meal and gone yesterday morning, when Mrs. Schlosser entered the kitchen, and asked the Chinaman, who is called Bing, if her breakfast was ready. He replied, very pleasantly, "Yes, your mush is on the table." The lady sat down, her back being toward the kitchen door, and had just prepared the dish for eating, when she received a terrible blow with some sharp instrument on the side of her head, back of the ear. She screamed, and ran through the house to the street, where her cries attracted a guard, who went at once for the murderer. Mrs Schlosser was found to have three ugly cuts, which penetrated the skull, and either of which may prove fatal. The prisoner is, we believe, in for murder, and worked a long time in the family of Capt. McAlester, of the former administration. We understand he was not considered vicious, but had spells of taking opium, when he would become sulky and refuse to work. He had been so good and agreeable of late that Mrs. Schlosser only the day before had given him a suit of under clothes, and just before the crime he was notably pleasant. Henry Schlosser is a man with legions of friends, and the injured lady is one of the salt of the earth, and there is no possible motive that can be divined for the assault. The only explanation so for is, that the fiend was probably crazed by opium. The hatchet with which the lady's head was chopped was found thrown out in the garden, and Bing walked up to the prison and gave himself up.
