¶1I. Defendant was convicted of killing Frank Crees, his stepfather. The conceded facts are that Frank Crees lived in a boathouse on the Mississippi River, in the city of Dubuque, with his wife and several children. The defendant, who was the son of Mrs. Clara Crees by a former marriage, went to Dubuque, after his discharge from the army, and resided with the Crees family until the night of August 17, 1919, when the boathouse was destroyed by fire. Frank Crees was one of the employees of the Chicago, Milwaukee & St. Paul Railway *364Company, and was last seen alive by anyone outside of the Crees family on the evening of August 14th, with his wife and children bathing in the river. His disappearance was observed shortly thereafter, and on Sunday morning following, the boathouse was totally destroyed by fire, leaving the Crees family destitute of money or clothing, except that worn by them at the time of the fire. The 'defendant and his mother stated that Crees had gone to Cincinnati, to look after some property in which he had an interest; that he would then go to Clinton; and that the family intended to float down the river to that place and meet him. On the evening of August 20th, some parties on the river observed an object afloat on the surface, a short distance from them, which they thought was a human body. They rode out to the object, and discovered that it was the body of a man. They tied a rope around the arm and towed the body to the shore. When it was removed from the water, it was found that a rope was wrapped around the body several times, and also around the neck, and that a rock weighing about 100 pounds was attached thereto. The ankles were also tied together. The body, which was in an advanced stage of decomposition, was clothed in a shirt only. After the body was taken to the undertaker’s, it was discovered that the skull was fractured in two places, either of the wounds being sufficient to have produced death. No one was called to identify the body. One witness testified that he had frequently seen the man in Dubuque, but did not know his name. The skin was badly discolored, and showed a tendency to slip from the flesh. Suspicion had already been aroused against the defendant, and, on August 20th, he was taken in custody by the sheriff, and, in the presence of Catherine Hibbe and the county attorney, signed a written statement, confessing that he killed Crees on the morning of August 15th, with a window weight, by striking him several times upon the head; that he tied a rope around his feet and neck; that he rowed the body out into the river, and attached a rock weighing about 100 pounds to the rope, and sunk the body in the river. No testimony was offered upon the trial on behalf of the defendant.
¶2*365
¶3Nothing appears to have been heard of Crees, nor was any testimony offered upon the trial to the effect that he had gone to Cincinnati, as claimed by the defendant and his mother. The corpus delicti may be established by circumstantial evidence. State v. Millmeier, 102 Iowa 692. While identification of the body by witnesses who knew Crees during his lifetime was not introduced, the circumstances shown fully justified the jury in finding that the body was that of Frank Crees. The evidence abundantly justifies the conclusion that he was murdered.

“I told him that I intended to go into this matter to the bottom; that I would sift it out. There were many other members of the family who would be able to throw some light on *366this matter, I was sure, before I finished my investigation; and I would continue to investigate the case if I had to bring'up the entire family and question each and every one of them separately. I was positive I would get the facts. He said, ‘What are you driving at ? What do you mean?’ I said,‘You needn’t ask that question of me; you know down in your heart what I mean. You know what you are up here for, and you know why I am questioning you. And you know that you have not told me the truth.’ ”
¶5This is the language which counsel for the defendant construes as a threat. It was during this conversation that the defendant confessed, saying, “Yes, I do know something about the death of Crees. I might as well come out with it.” Later, the county attorney, in the presence of the chief of police and the police matron, wrote the statement which was signed by the defendant. This statement recites that it “is -voluntary, without threats, promise, or inducement of any kind.” Both the chief of police and the police matron testified that the statement was read over to him, and that he signed the same freely, and that nothing was done by any of the parties present to induce him to do so.
¶6The court submitted the question to the jury by instructions to which no exception was taken. The chief of police testified that he used no persuasion, promises, or other inducements to obtain the confession. The court could not have found, as a matter of law, that the confession was improperly obtained, and this question was, therefore, properly submitted to the jury. State v. Bennett, 143 Iowa 214. The confession was properly received in evidence.
¶7III. One McCarthy testified that the defendant told him that he killed Crees with a window weight on Friday night; that these statements were made by the defendant voluntarily, and without threats or promises of any kind. The court properly overruled defendant’s objections to the testimony of this witness, which were based upon the same grounds as the objections to the testimony of the chief of police.

“October 7th, 1919.
“Mrs. Clare Crees, Dear M. Frend. Here is some good advice to you. Swear that James Killed Frank in defense. Say that he had that big English knife in his hand, atrying to cut the underclothes off the girls. Say that James dragged Frank back from the girls and Frank hit James with the knife. Say James hit him with the iron weight which was on the floor. Say you saw the knife in his hand. The rest after that the same as before. As much as you remember. Learn by heart.
“[Signed] Mathew F. Marsun.
“ (Give the sign if you get this letter.) ”
¶9The letter was never received by his mother, and she did not testify as a witness. Death was caused by blows upon the head with a blunt instrument, and the manner in which the body was placed in the river leaves no doubt that Crees was murdered. The evidence fully and abundantly sustains the verdict.
¶10
¶11VI. Complaint is also made of the refusal of the court to give a requested instruction. No exception was taken to the refusal of the court to give this instruction, and its substance was embodied in a separate paragraph of the court’s charge to the jury. Some other alleged errors are • discussed by counsel, but they are without substantial merit. We have read the entire record with care, and are satisfied that the verdict of the jury was right, and that no prejudicial error was committed by the court. It follows that the judgment below is — Affirmed.
