The defendant, Tilda Miner, thirty-seven years of age, was the wife of Edward Miner, sixty-four years of age. Under the record, there can be no question that Edward Miner died February 25, 1930, as the result of strychnine poisoning. His death, if not accidental or suicidal, was brought about by *Page 194 means of poison, so as to constitute murder in the first degree. There is evidence from which the jury could find that the defendant and also Hartwig were guilty of the crime. There is some evidence to the effect that the defendants were infatuated with each other; that on February 20th Hartwig procured from the drug store at Olin, where all of the parties reside, one eighth of an ounce of strychnine for the expressed purpose of killing rats; that strychnine was placed in capsules, and these capsules placed in a small box with other capsules containing medicine which the deceased had been taking for an ailment. The jury could find from the evidence that the capsules were placed in the box by either the appellant or Hartwig. There is no direct evidence that either of the defendants gave or administered strychnine to Edward Miner, and he was up and around the house and able to get his medicine.
[1] The court, in one of the instructions, told the jury that the county attorney's information jointly charges the defendants Miner and Hartwig with the crime of murder, for which the defendant Miner is now on trial, and then proceeded:
"Under the law of this state the distinction between an accessory before the fact and a principal is abrogated, and all persons concerned in the commission of a public offense, whether they directly commit the act constituting the offense, or aid and abet its commission, though not present, must be indicted, tried and punished as principals.
"You are instructed that even though the true information charges this defendant as a principal she may be convicted on proof beyond a reasonable doubt that she aided and abetted the commission of the crime charged herein."
The appellant complains because of the giving of this instruction. It is her contention that there is no evidence from which the jury could find that she was an accessory before the fact; that, under the evidence, if guilty at all, she was only guilty as a principal. The jury could find from the evidence, as disclosed by the record, that all that was manually and physically done in the procurement of the strychnine and placing the same in the box of medicine was done by Hartwig. If this be true, then Hartwig was a principal. The jury could also find from the evidence, as disclosed by the record, that what, if anything, *Page 195 was done by the defendant, Miner, was done by her in aiding the act or acts committed by Hartwig. Therefore, it was proper for the court to give an instruction as to the liability of an accessory before the fact.
[2] The appellant further urges that the aforesaid instruction is erroneous in the last paragraph, in that it omits the element of knowledge on her part of the act upon which she could be convicted as an accessory before the fact. There is merit in this contention. In State v. McCarty, 210 Iowa 173, the court gave to the jury the following instruction:
"`So, in this case, if you find that the state has established beyond a reasonable doubt that the defendant aided, abetted, assisted, advised, or encouraged any other person to commit the crime charged in the indictment, you should return a verdict of guilty.'"
We held this instruction erroneous, in that the element of knowledge is therein omitted, saying: "Knowledge is a necessary element to constitute an accessory."
The aforesaid instruction is the only one given on the subject. Our holding in the cited case is controlling in the instant case. It is therefore apparent that the aforesaid instruction is erroneous, and for the giving of the same prejudice is presumed, and we cannot hold, as contended by the State, that it is unprejudicial to the defendant.
Our holding relative to the aforesaid matter makes it unnecessary to consider the other matters urged upon us for a reversal, none of which are likely to arise on a new trial. The judgment of the trial court is hereby reversed and the cause remanded for a new trial. — Reversed.
