the fifth amendment.
The fifth amendment protects you against testifying against yourself.
Question is unclear. Is the dead person the one who committed the offense, OR - - Did the family of the dead person commit the crime? In the first case, if the perpetrator is dead there will be no testifying because there will be no trial or hearing. In the second case, there is no bar to testifying against the family of someone who happens to be deceased.
His mandate is "the quest for justice." He is the "people's prosecutor." His function is to prosecute crimes committed against the "people of the state."
To press criminal charges against someone, you typically need to report the crime to the police. The police will investigate the matter and gather evidence. If they believe a crime has been committed, they will forward the case to the prosecutor's office. The prosecutor will then decide whether to file formal charges against the individual.

The prosecutor.
By testifying against him.
the accused person
The Fifth Amnedent provides the right to not incriminate oneself. What that means is if you are on trial, or a witness testifying at a trial, you are not required to answer any question that would provide evidence that you commited another crime.
A Prosecutor
YOU cannot have the charges dropped by yourself. Such an assault is a crime against the state and only the prosecutor can 'drop' the charges. If you are a reluctant 'complaining witness' speak to the prosecutor about your hesitation to go forward.
