Middletown, Conn., May 22.–The preliminary trial of Clarence E. Murphy, charged with having caused the death of his mother, Ellen Murphy, ended yesterday afternoon in Durham. Murphy was held for trial at the superior court criminal term next September, without bail. He was taken to Haddam jail. The trial was full of expert medical testimony. The defense held that death was wholly caused by epileptic fits, the result of a long spree. Murphy’s wife and two babies were with him during the trial, and the wife nearly fainted when the mother’s skull was produced and the doctors described the autopsy. Murphy never flinched or turned a shade paler.
