At eight o'clock last night Officer O.H. Smith, of the Fourty-fourth Precinct, arrested George H. Powell, a butcher doing business in Washington Market and residing in Marcy, near Myrtle Avenue, who is charged with being an accomplice in the death of Susannah Lattin, of Farmingdale, Long Island, who decease[d] at the alleged private lying-in asylum of Dr. Grindle, No. 6 Amity Street, New York, has already been noticed in the [Brooklyn] Eagle. It is alleged that a few months since Powell hired some furnished rooms on Myrtle Avenue, near Ryerson Street, to which place it is stated he took Miss Lattin and introduced her as his wife. It is also alleged that after living with her there as his wife, he afterwards took her to No. 6 Amity Street for treatement, and introduced her there also as his wife. It will be remembered that Daune, Dr. Grindle's student, who testified at the inquest commenced by Coroner Rollins on Saturday, recognized Powell as the man who had called on the deceased several times before her death, and from whom at her desire, he obtained the necessary instructions for forwarding a letter to her parents, when Dr. Finell of West Houston Street informed her of the precarious state she was placed in. Powell is 38 years of age a butcher by trade, and is married. He was sent last night to the Fifteenth Precinct Station House in New York to await the action of Coroner Rollins, who will resume the investigation relative to the cause of Miss Lattin's death on Thursday next.
