What does it mean when you have a inbound detainer request intrastate unindicted warrant and your already serving time in prison?

An inbound detainer request for an intrastate unindicted warrant means that law enforcement in a different jurisdiction has issued a request to hold you for a potential charge, even though you haven't been formally indicted. This can occur while you are already serving time in prison, indicating that authorities may want to bring you in for questioning or to prosecute a separate case. Essentially, it means there may be additional legal issues pending against you that need to be addressed once you are released or transferred.
