"The burden of proving everything essential to the establishment of the charge against the defendants, and each of them, lies on the prosecution, and even if it were conceded that somebody murdered Dr. Cronin, yet the defendants are not required nor expected to prove who committed the murder.

"The prosecution is required to prove beyond all reasonable doubt that the defendants, and not somebody else, committed the crime charged in the indictment. It is insufficient to justify you in convicting the defendants, that the evidence disclosed that Patrick H. Cronin was murdered, and that the defendants, or somebody else, murdered him, or that the probabilities are that the defendants and not somebody else murdered him.

"You ought not, and can not legally convict the defendants, or either of them, upon the mere doctrine of chance and probability. Although you may believe that it is highly probable and very likely that the defendants are guilty, and even that it is far more likely and probable that they are guilty than that they are innocent, yet, no amount of suspicion will warrant you in finding a verdict of 'guilty' against the defendants, or any of them.

"To warrant a conviction upon a charge of murder, the evidence must be of such kind and quantity as to convince the jury of the truth of the charge beyond every reasonable doubt, and to a moral certainty. If, therefore, when you, without passion, prejudice, or bias, have fairly and honestly considered the entire evidence on both sides of the case, do not feel morally certain, to the exclusion of every reasonable doubt, of the guilt of the defendants, then it is your duty to acquit them.

"It is the duty of the jury to examine the evidence on both sides of the case without any feeling of resentment or revenge, and if, after such examination, you entertain any reasonable doubt as to whether the deceased was murdered by the defendants as charged in the indictment, or by somebody else, you should acquit the defendants; in other words, if the evidence, after an impartial consideration, leaves your mind in a state of reasonable doubt as to whether any particular defendant is guilty, as charged in the indictment, then such defendant should be acquitted.

"If the evidence in this case fails to show any motive on the part of the defendant to commit the crime charged against him, then this is a circumstance in favor of his innocence, which the jury ought to consider in connection with all the other evidence in the case in arriving at a verdict.

"An individual juror ought not to compromise any well-founded doubt of guilt that he may entertain respecting the defendants or any of them with his fellow-jurors. The jury can agree only to convict or acquit, and you can only properly convict when the guilt of the defendants is so fully and clearly proven to the mind of each individual juror, as to exclude every reasonable doubt of guilt.

"A reasonable doubt is that state of the case which, after the entire comparison and consideration of all the evidence in the case leaves the jurors in that condition that they can not say they have an abiding conviction, to a moral certainty, of the truth of the charge. It is not sufficient to establish a probability, though a strong one, that the fact is more likely to be true than the contrary, but the evidence must establish the truth of the fact to a reasonable and moral certainty; a certainty that convinces and directs the understanding and satisfies the reason and judgment of the juror who is bound to act upon it conscientiously.

"In considering the case, however, the jury are not to go beyond the evidence to hunt up doubts, nor must they entertain such doubts as are merely chimerical or conjectured. A doubt to justify an acquittal must be reasonable, and it must arise from candid and impartial investigation of all the evidence in the case, and unless it is such that were the same kind of doubt interposed in the graver transactions of life, it would cause a reasonable and prudent man to hesitate and pause, it is insufficient to authorize a verdict of not guilty. If, after considering all the evidence, you can say you have an abiding conviction of the truth of the charge, you are satisfied beyond a reasonable doubt.

"The doubt which the juror is allowed to retain in his own mind, and under the influence of which he should frame a verdict of not guilty, must always be a reasonable one. A doubt produced by undue sensibility in the mind of any juror in view of the consequence of his verdict is not a reasonable doubt, and a juror is not allowed to create sources or materials of doubt by resorting to trivial and fanciful suppositions, and remote conjectures as to possible states of facts, differing from that established by the evidence. You are not at liberty to disbelieve as jurors, if, from the evidence, you believe as men; your oath imposes on you no obligation to doubt where no doubt would exist if no oath had been administered.
