1. Witnesses — Cross-Examination of Defendant as to His Voluntary Testimony at Coroner's Inquest. A defendant testifying at a coroner's inquest before any charge has been filed against him and without any objection on his part does so voluntarily, and on cross-examination it is permissible to confront him with this testimony, and cross-examine him with reference thereto.
2. Evidence — "Involuntary" Statements or Confessions. Involuntary statements or confessions are ones that are extracted by any threats of violence, or obtained by direct or implied promises, or by the exertion of improper influence.
3. Witnesses — Cross-Examination of Defendant — Waiver of Constitutional Privilege of Silence. When a defendant takes the witness stand in his own behalf, he waives his constitutional privilege of silence, and the prosecution has the right to cross-examine him upon his evidence in chief the same as any other witness, and to the same extent.
4. Same. By such cross-examination defendant is not denied his constitutional right that "no person shall be compelled to give evidence which will tend to incriminate him."
5. Coroners — When Coroner's Inquest Proper. A coroner's inquest should only be held over the bodies of persons the cause of whose death is unknown, and who are supposed to have died from unlawful means.
