Ziang Sung Wan v. United States/Opinion of the Court
On January 31, 1919, the police department of the District of Columbia learned that three Chinamen, the inmates of a house in Washington occupied by the Chinese Educational Mission, had been murdered. They were known to have been alive late in the evening of January 29. Police officers were told by Li, a student, that, earlier on the same evening, he had seen at the Mission a resident of New York City named Wan. Acting under instructions of the superintendent of police, two detectives started immediately for New York, taking Li with them. On February 1, they entered Wan's room in a lodging house, found him there, and brought him to Washington. He was not formally arrested until February 9. Later, he was indicted, in the Supreme Court of the District, for the murder of one of the Chinamen; was found guilty; and was sentenced to be hanged. The Court of Appeals of the District affirmed the judgment. 289 F. 908, 53 App. D. C. 250. A writ of certiorari was granted. 263 U.S. 693, 44 S.C.t. 34, 68 L. Ed. 509.

The main question for decision  is whether, on the facts disclosed in the testimony of the superintendent of police, three detectives and the chief medical officer of the jail, the trial court erred in admitting as evidence statements made by the defendant to the police officers before and shortly after his formal arrest.  Four of the statements were oral. These, if admissible, were important evidence. The fifth was a stenographic report of an interrogation of the defendant conducted by the detectives, after the arrest. This report contained a full confession. The introduction of each of the statements was duly objected to on the ground that the government failed to show that it had been voluntarily made and that from the testimony of its own witnesses the contrary appeared. The court admitted the statements. It later charged the jury:

'The test of the case, and the inquiry that you will have to make in answer is, Did the questioning, did the physical      condition, did the importunate questioning, if you choose to      call it so, render the confession made by the defendant not      his own; but did it substitute for his will the will of      another, and thus was it or not his voluntary act?'

Wan was a native of China. He had come to the United States in 1916, at the age of 22, as a student. In 1918, he engaged in a business which proved unsuccessful. Since December of that year, or earlier, his health had been bad. He had an attack of Spanish influenza. He suffered continuously from a chronic stomach trouble which led him to eat sparingly and irregularly. When the detectives entered his room unannounced they found him in bed. They had no search warrant; but they made a search of the room and his effects, including the bed in which he lay. They were accompanied by a New York police officer; but they did not arrest Wan. They requested that he return with them to Washington. He told them he was too sick. Li, who had been left waiting outside the closed door and was called in, told Wan that both of them were suspected of the murder. Then, Wan consented to go with the detectives to Washington.

On arrival in Washington, Wan was not put formally under arrest; but he was taken to a secluded room. In the presence of three detectives, the superintendent of police, and Li, he was subjected there to questioning for five or six hours. Late in the evening of that first day, the detectives took him to Hotel Dewey; and, without entering his name in the hotel registry, placed him in a bedroom on an upper floor. In that room he was detained continuously one week. Throughout the period, he was sick and, most of the time, in bed. A physician was repeatedly called. It was a police surgeon who came. In vain Wan asked to see his brother, with whom he lived in New York, who had nursed him in his illness, who had come to Washington at his request in January, who had returned with him to New York, and whom, as he later learned, the detectives had also brought to Washington, were detaining in another room of the hotel, and were subjecting to like interrogation.

Wan was held in the hotel room without formal arrest, incommunicado. But he was not left alone. Every moment of the day, and of the night, at least one member of the police force was on guard inside his room. Three ordinary policemen were assigned to this duty. Each served eight hours; the shifts beginning at midnight, at 8 in the morning, and at 4 in the afternoon. Morning, afternoon, and evening (and at least on one occasion after midnight) the prisoner was visited by the superintendent of police and/or one or more of the detectives. The sole purpose of these visits was to interrogate him. Regardless of Wan's wishes and protest, his condition of health, or the hour, they engaged him in conversation. He was subjected to persistent, lengthy, and repeated cross-examination. Sometimes it was subtle, sometimes severe. Always the examination was conducted with a view to entrapping Wan into a confession of his own guilt and/or that of his brother. Whenever these visitors entered the room, the guard was stationed outside the closed door.

On the eighth day, the accusatory questioning took a more excruciating form. A detective was in attendance throughout the day. In the evening, Wan was taken from Hotel Dewey to the Mission. There, continuously for ten hours, this sick man was led from floor to floor minutely to examine and re-examine the scene of the triple murder and every object connected with it, to give explanations, and to answer questions. The places where the dead men were discovered; the revolver with which presumably the murder was committed, the blood stains and the finger prints thereon; the bullet holes in the walls; the discharged cartridges found upon the floor; the clothes of the murdered men; the blood stains on the floor and the stairs; a bloody handkerchief; the coat and pillow which had been found covering the dead men's faces; photographs, taken by the police, of the men as they lay dead; the doors and windows through which the murderer might have entered or made his escape; photostat copies of writings, by means of which it was sought to prove that Wan was implicated in a forgery incident to the murder; all these were shown him. Every supposed fact ascertained by the detectives in the course of their investigation was related to him. Concerning every object, every incident detailed, he was, in the presence of a stenographer, plied with questions by the superintendent of police and the detectives. By these he was engaged in argument; sometimes separately, sometimes in joint attack. The process of interrogation became ever more insistent. In passed at times from inquiry into command. From 7 o'clock in the evening until 5 o'clock in the morning the questioning continued. Before it was concluded, Li, who was again in attendance, had left the Mission about midnight, worn out by the long hours. The superintendent of police had returned to his home, apparently exhausted. One of the detectives had fallen asleep. To Wan, not a moment of sleep was allowed.

On the ninth day, at 20 minutes past 5 in the morning, Wan was taken from the Mission to the station house and placed formally under arrest. There the interrogation was promptly resumed. Again the detectives were in attendance, day and evening, plying their questions, pointing out alleged contradictions, arguing with the prisoner, and urging him to confess, lest his brother be deemed guilty of the crime. Still the statements secured failed to satisfy the detectives' craving for evidence. On the tenth day, Wan was 'bundled up,' was again taken to the Mission, was again questioned there for hours, and there 'the whole thing was again talked of and enacted.' On the eleventh day, a formal interrogation of Wan was conducted at the station house by the detectives in the presence of a stenographer. On the twelfth day, the verbatim typewritten report of the interrogation (which occupies 12 pages of the printed record) was read to Wan, in his cell at the jail. There he signed the report and initialed each page. On the thirteenth day, for the first time, Wan was visited by the chief medical officer of the jail, in the performance of his duties. This experienced physician and surgeon testified, without contradiction, to the condition of the prisoner:

'[He] found * * * [Wan] lying in a bunk in the cell, very      weak, very much exhausted, very much emaciated; he complained      of abdominal pain, which was rather intense. He told witness,      and witness afterwards saw, that he vomited if he attempted      to take food; that it was difficult or impossible for his      bowels to move unless they were assisted by an enema; witness      thought he was very seriously ill; * * * ordered certain      tests by the laboratory; * * * had his blood examined and his      abdomen X-rayed and had him removed from the cell to the Red      Cross room; * * * concluded he was suffering from spastic      colitis [involving contraction of the bowels]. * * * The      result of that contraction would be almost constant pain,      excited by any further additions to the contents of the tract      at that point, and vomiting and persistent constipation. * *      * Witness knows defendant was in bed at least a month after      his treatment was prescribed. From witness' observation and      medical experience, judging from the defendant's emaciation      and history he gave witness, and his condition generally,      would say that when witness saw the defendant on February      13th he had been ill for a matter of weeks. * * * He told me      he had been talked to all one night and had not received any      medical attention, and had been in constant pain all of this      time and had been unable to eat for days, and considering all      those facts I came to the conclusion that he was so exhausted that he was really-he told me also      that he had signed a confession.'

Then the witness was further questioned by the court:

'Question. You thought he was so exhausted mentally that he      would not know what he was signing. * * * Would he know what      he was signing?

'Answer. He would know what he was signing, yes.

'Question. Would he be liable to sign a confession that would      lead him to the gallows in that condition?

'Answer. I think he would, if he wanted to be left alone.

'Question. With spastic colitis, if he was accused of crime      he would simply sign a paper and say, 'You hang me'? This is      your opinion as a medical man?

'Answer. I say, if he was as sick as that, and in as great      pain as that, he would do anything to have the torture      stopped.'

The Court of Appeals appears to have held the prisoner's statements admissible on the ground that a confession made by one competent to act is to be deemed voluntary, as a matter of law, if it was not induced by a promise or a threat, and that here there was evidence sufficient to justify a finding of fact that these statements were not so induced. In the federal courts, the requisite of voluntariness is not satisfied by establishing merely that the confession was not induced by a promise or a threat. A confession is voluntary in law if, and only if, it was, in fact, voluntarily made. A confession may have been given voluntarily, although it was made to police officers, while in custody, and in answer to an examination conducted by them.  But a confession obtained by compulsion must be excluded whatever may have been the character of the compulsion, and whether the compulsion was applied in a judicial proceeding or otherwise. Bram v. United States, 168 U.S. 532, 18 S.C.t. 183, 42 L. Ed. 568.  None of the five statements introduced by the government as admissions or confessions was made until after Wan had been subjected for seven days to the interrogation. The testimony given by the superintendent of police, the three detectives and the chief medical officer left no room for a contention that the statements of the defendant were, in fact, voluntary.  The undisputed facts showed that compulsion was applied. As to that matter there was no issue upon which the jury could properly have been required or permitted to pass. The alleged oral statements and the written confession should have been excluded. 

Reversed.
