I'm writing a story and I'm asking for factual accuracy in the storyline. (Not asking for suggestions in hiring an actual PI.)
I know for a fact that it's now illegal in Korea to hire a Private Investigator ("Detective") for purposes such as tracking your spouse to see if they're cheating, etc.
However, is hiring a Private Investigator for a CRIMINAL TRIAL possible? To collect evidence and maybe track down a potential witness or suspect. In the US it's not only legal, but common, to hire a Private Investigator to collect evidence and interview people.
If hiring Private Investigators is not allowed, then what's the closest option besides the police? Is the police the only other option for collecting evidence like so?
My story really needs someone to do the evidence collecting, witness interviewing, and suspect-tracking-down job.. How can I make this work? I heard that attorneys don't really do jobs like these.. Do I need to make it so that the police takes care of these things?
Thank you, I don't know where else to ask. I might ask over at /r/legaladviceofftopic or something..
