Any smart lawyer is going to know that there is no way in hell the murder charge is going to stick. Hell, it's not even going to fly at manslaughter.
Incorrect. A smart lawyer is going to advise the accused plead for a sentencing deal. Anyone who believes the charges won't stick or will be overturned on appeal is reading the statute incorrectly:
A person also commits the crime of murder in the first degree, regardless of malice
if the death of a human being results from
robbery with a dangerous weapon
Those are the elements of the offense. Whether the human death is an accomplice, target, or bystander is irrelevant, as are the actions of the accused. In Oklahoma, according to state law, if someone commits robbery with a weapon and a person dies in the process, the accused is guilty of first-degree murder. Intent is not a necessary component, as indicated by the phrase "regardless of malice." Intent is only necessary to establish the actus reus element of the robbery, not the murder. To elaborate, the way the statute is written the prosecution will need to prove the following to ensure a first-degree murder conviction:
1. Accused intended to commit robbery.
2. Accused took action to attempt a robbery.
3. Said action included the use of a dangerous weapon.
4. A human death resulted from the robbery.
If those four conditions are met in the prosecution's case, the accused must be found guilty of first-degree murder under Oklahoman law.
In order for the charge to be found invalid or overturned on appeal, a challenge would have to be made against the statute itself to show it is inconsistent with the state or federal constitutions.
This isn't creativity on the part of the charging agency or DA, under state law it is a perfectly acceptable charge.
