That is not the same thing as finding that the person did not murder him. That's why the verdicts are "'guilty' or 'not guilty'", and not "'guilty' or 'innocent'."
Take for example a hypothetical situation where I murdered someone. The prosecutor decides to prosecute me under murder in the first degree, that is, premeditated murder. However, the murder was actually in a fit of passion, and the evidence for murder-1 isn't there. The jury can find me not guilty of murder-1, even if they believe I committed the murder, because the prosecution messed up and filed the wrong charge (and didn't also charge me with murder-2 or homicide as a backup). Thanks to double jeopardy, I can't then be re-charged.
Everyone can agree that I murdered that person, including me, even though I was acquitted. Jut because someone was acquitted of murder for a death they caused doesn't automatically mean the the person killed wasn't murdered.
Take a look at the Wikipedia entry at https://en.wikipedia.org/wiki/Murder_of_Nicole_Brown_Simpson... where it says Nicole Brown Simpson and Ron Goldman were murdered, and says that O. J. Simpson was acquitted for those murders.
According to your reasoning, were Nicole Brown Simpson and Ron Goldman murdered? The page later points out "In 1997, the jury unanimously found Simpson responsible for the deaths of Goldman and Brown."
Quoting now https://en.wikipedia.org/wiki/James_Coyle:
> James Edwin Coyle (March 23, 1873 – August 11, 1921) was an American Catholic priest who was murdered in Birmingham, Alabama, by a Ku Klux Klan member for performing a marriage between Pedro Gussman, a Puerto Rican Catholic, and a recent Catholic convert, Ruth Stephenson. The killer, E. R. Stephenson, was Ruth's father and opposed what he saw as an interracial union. He would ultimately be acquitted by a jury.
Was Coyle murdered? Wikipedia seems to think so, and lists him under "People murdered in 1921" at https://en.wikipedia.org/wiki/Category:People_murdered_in_19... .
The Wikipedia entry states that a jury found that the person who killed him did not murder him. If what was done to him was not murder, then he was not murdered.
Therefore the iOS summary is wrong.
