From the August 25, 1898 New York Times:

“Anton Wozonecski, twenty-seven years old, died at his home, 173 Eleventh Street, Jersey City, at midnight on Tuesday from poison administered by his wife through mistake. Wozonecski was suffering from an attack of bilious colic and a neighbor suggested that he should take a dose of rochelle salts.

Mrs. Wozonecski went to Freeman Stoddard’s drug store, 557 Grove Street. She says she asked for rochelle salts. She speaks English imperfectly. Mrs. Stoddard says she simply asked for ‘roach.’ He though she wanted an insect powder and gave her one. This is borne out by the package that contained it. It was originally marked ‘Persian powder,’ but this had been scratched out and the words ‘roach powder’ were written in its place.

Mrs. Wozonecski gave her husband the poison. He soon became worse and then Dr. Finnerty was called in, but when he arrived Wozonecski was dead.”
