My question involves police conduct in the State of: nevada
So my mom cleans houses and she cleaned a house for a certain a old man, So she finished the job got paid and left. About a week later he called and accused her of stealing, she denied it and then he called atleast 30 times in less than two days leaving racist and threatening messages which are all recorded. We recently got a call from a detective, always a month later asking her to come in alone for questioning and wanting her to sign something(he also asked she was legal -_-). I looked up the detectives info and it seems legit but I'm not sure if she should go into questioning considering I can't go with her because of my work schedule. Can she get in trouble for not going in to talk to the detective? It's super far he can't he just come here? I don't really a case against her anyways
