Question is somewhat unclear. If the questioner is asking where the perpetrator goes and how they are handled - - when first arrested they would go to the local law enforcement holding or detention facility (or country jail). They would then be presented to court for arraignment and then (depending on the jurisdiction) housed in the county jail awaiting, and during, their trial. If convicted they would more than likely be transferred to a state prison to serve their sentence.
Sure, you can be arrested for murder, if the stabbed person dies. You can also be tried for murder. "Self Defense" is a legal defense to a criminal charge of murder. Self Defense is a defense to a criminal charge and in a criminal trial. It has nothing to do with being arrested.
* Of course she would be charged with murder. Planned murder is first degree murder and accidentally killing someone (if you push them and they hit their head and die) one might get off with a charge of second degree murder. It is only a fool that would reduce themselves to murdering an ex mate because it proves nothing and it sure is not worth doing prison time! Also when a husband and wife are murdered or they have disappeared their spouse is generally the first person the police suspect. With DNA evidence it's highly doubtful anyone would get away with murdering their spouse or ex spouse.
Tried for murderNo, because you can't charge a dead person. That would be a waste of the court's time to spend tax dollars charging a dead person with a crime.They wouldn't charge a suicide victim with murder any more than they would charge a dead person with murdering someone else.More accurately, it is because the killer would be unable to appear at trial. Imagine that the killer did not commit suicide, but fled the country. A trial could not be conducted in his absence. He would have to be located first and then tried.
If that person dies due to the injuries cause from the attempted murder then you can be charged with murder. But if you are convicted of attempted murder prior to that, double jeopardy would prevent you from being convicted of murder
A person charged with an "open count of murder" typically has been charged with an intentional killing of another person, but the State does not yet know what degree of killing the evidence would eventually prove at trial. New Mexico's homicide laws separate intentional killings into three crimes: First-degree Murder, Second-degree murder, and Voluntary Manslaughter. First-degree murder is further separated into three types: Willful and deliberate murder (what we'd call "premeditated murder"), Felony murder, and Depraved Mind Murder (a killing by any act dangerous to the lives of others, indicating a depraved mind that is indifferent to human life). New Mexico Statutes Annotated 1978, Sections 30-2-1 and 30-2-3
If you knew that a crime was to be committed, or if a reasonable person would believe that you could have prevented the crime, the answer is "yes", you can be charged as well.
Absolutely not ! That would result in you being charged with murder - as you're planning to kill the person.
Premeditated violent murder
Yes it is but technically, even though the actions charged are the same the laws charged have to be different. It has happened that a person has been found innocent of a murder in a state court, but later charged with and found guilty of violating or depriving the victim of his/her civil rights by causing the murder. The action is the same, the murder, but the charges are different. This is actually a very fine distinction and not everyone would agree that this is not a violation of the right against double jeopardy.
It depends entirely on the circumstances. It would have to be considered plausible ie. witnesses, admissions etc. But similarly, you would have a case for reasonable doubt for a 'murder'. The Law is not black and white in many cases, this would be a grey area that could be argued both ways.
Either assault or attempted murder. If you used a weapon it would be assault with a weapon/deadly weapon.
I just found out this week that in Oklahoma you can not be charged with attempted murder. They have to charge you with something else.
