If I know someone who has a warrant from another state living in Kenosha, what should I do??

Well I would definitely give any information you have to the local law enforcement department.

Depends on the type of warrant. If it's a serious felony, that state will come pick up from kenosha jail.

Depends on the warrant and where it is from. If the state it is out of says it will extradite then KPD will act on it. If not they wont. Hope this helps.
