Will evidence be presented as it pertains only to Sierah Joughin's case?? Or will they present evidence that he's a serial killer? How will other crimes he's responsible for be solved if come into play??
Hard to know for sure, but most likely only evidence of crimes committed against Sierah in Fulton County.
Unless they have evidence of any other specific crimes committed in Fulton County against other persons.
In that case, they could conceivably seek additional charges that are not specifically related to the crimes committed against Sierah.
I don't know if that is a desired outcome at this point in time, IMO, unless they do have solid evidence of crimes against other persons in Fulton County.
Better to focus on convicting him for Sierah than to shoot too broad and spread the prosecution resources too thin.
They can always proceed against him with other crimes at a later date if they believe they have sufficient evidence.
The Fulton County grand jury has jurisdiction only over crimes committed in the county.
Some leeway exists as to what they can say and present to a grand jury as opposed to what would pass muster in a trial courtroom.
IANAL, so I am unsure, but they might be able to work in that some of the evidence found in his possession suggests that there may be other victims.
That shouldn't be necessary to get indictments for murder and kidnapping, as far as I can tell from what is revealed in the search warrant affidavits.
Proving probable cause to indict him for the crimes committed against Sierah should not be difficult.
Solving any other crimes he may have committed falls to law enforcement. BCI is in a position, as is the FBI, to work as a central coordinator if the crimes occurred in multiple jurisdictions.
If they feel strongly that he is in fact a multi-jurisdictional serial killer, I suspect that they have already (or are in the process of) forming formal and/or informal investigative groups to focus on gathering and assembling the evidence.
Any future prosecutions would take place in the jurisdictions where the crimes occurred. Sometimes that resides in the county where a body is found when it cannot be determined where a person was kidnapped and/or murdered.
