A man holding his hands to his throat, with the front of his clothing covered with blood, came dashing out of the tenement house No. 141 Thompson street, New York, 10 o'clock this morning, and then a woman ran from the same house crying: "Stop him! Stop him! He has committed a murder." Roundsman McCormick, who was in a Seventh avenue car, on his way to the Court of General Sessions, heard the cry, and seeing the man, got off the car and arrested him. Then Officer Ryan, of the Eighth Precinct, who has Thompson street for a post, arrived on the scene. Telling the roundsman to take his prisoner to the Prince street station, he went to No. 141, and ascended the stairs, on the first floor above the street, just where the hall landing begins he beheld a most sickening sight.

LAYING IN A POOL OF BLOOD that extended for several feet around her, lay a woman with her throat cut from ear to ear. So deep was the gash that the head was nearly severed from the body. She was stretched half within a room, the door of which was ajar, and half way in the hall. Her head and shoulders being within the apartment. A crowd of horror stricken women and children stood about her.

No one at first seemed to know how the woman got there or who had killed her. None had seen the brutal deed committed. Blood stained the whole hallway leading to a door of one of the front rooms.

On inquiry, the officer learned that the woman was Mrs. Mariette Renaut, the housekeeper of the tenement, a respectable married woman and the mother of five children, the eldest of whom is 22 years old and the youngest 8 years old. Her husband, August Renaut, a carpenter, works at No. 265 Grand street. The circumstances of the murder, as far as could be learned, are as follows:

At six o'clock this morning the murdered woman's husband left his home to go to his work. The wife was up at the time, attending to the household duties. Toward eight o'clock the eldest three boys went to their employment and the youngest boy went into the street to play. The daughter Clementina, a child of twelve years, was not well and lay in bed, ordered by a physician not to leave it all day. The Renaut family occupy the front room, on the first floor from the street. it is a large apartment divided in the centre by a kind of alcove. In the front portion of the apartment were two sofa beds on one of which slept the little girl.

At 10 o'clock the child was suddenly aroused by HEARING HER MOTHER SCREAM. She hurriedly arose and looked around. The door leading to the hall was partially open; the floor near the door was covered with blood. The child slipped on a dress and ran into the hall. In the rear of which near the head of the stairs and half way within a rear room she saw her mother lying dead, with her throat terribly severed. Throwing herself upon the body of her prostrate parent, the child went into hysterics and was removed into the room of a kindly neighbor.

Shortly before the child ran into the hall, Mrs. Maggie Bott, who occupies the rear room of the same floor on which the Renaut family reside, left her apartment to get a pitcher of water from a hydrant that stands in the hall. Just then she saw a man, bleeding at the neck, dash down the stairs holding a blood stained razor in his hand. Then she saw Mrs. Renaut run from her room toward the hydrant. She held her two hands to her neck, and Mrs. Bott thought that she desired to wash herself. Then she saw blood streaming from between her fingers. The next moment Mrs. Renaut cried: "My God! I'm murdered!" and fell to the floor, partially in the hall, and partially in Mrs. Bott's room. The blood gushed from the wound in her throat, covering the floor. Then Mrs. Bott rushed into the street, crying "Murder."

The details of how the murder was committed are not known, but from the blood stains upon the floor and wall of Mrs. Renaut's room, it is thought that it was committed there. The murderer must have knocked for admittance into the room, and Mrs. Renaut opened the door. he then made his demands upon her, which she refused to listen to, and probably ordered him out. He then drew a razor and drew it across her throat. The blood splashed wall indicates this. He then cut his own throat and fled into Thompson street. The razor was found at the foot of the stairs.

Roundsman McCormick took his prisoner to the Prince street Station, where an ambulance was telegraphed for. One soon arrived from the St. Vincent Hospital. The surgeon in attendance bound up the wound in the man's throat. He was then able to speak, and said his name was Amedeo Begot, 41 years old and that he lived at No. 109 Thompson street. He could only speak in gasps, and was unable to answer any of the questions put to him in relation to his double crime. His injury is very dangerous, if not fatal. He was taken to the hospital.

Roundsman Larkin, with this information, was sent to the scene of the tragedy to gather further information. When he got there the body had not yet been disturbed. August Renaut, the dead woman's husband, arrived at nearly the same moment. His little son had run to his work shop and told him that his wife was dead. On seeing the horrible sight he at first appeared dazed. Then he suddenly dropped upon his knees BY HIS DEAD WIFE'S SIDE. He felt her wrist, her face and put his hand at her heart. He seemed to disbelieve that she was dead. The The whole truth and horror of the scene suddenly flashed through his mind. He sank upon the cold body and uttered a groan of anguish that almost sent a thrill of terror to those standing near. Then he gave way and cried like a woman. A friend spoke to him, and he arose to a standing position, and going into his own room, opened one of the sofa beds, placed upon it a mattress. He went back to where his wife lay. Picking her tenderly up he carried her to the couch he had prepared, and placed her upon it. He sat down by her side and covered his face with his hands. The child, Clementina, was brought down stairs to comfort him, but, on seeing her dead mother, the child was seized with a fit of screaming and fainted.
