Okay so I have been seeing this girl and her ex is insane, he sent me death threats saying "he would kill me" and "he would enjoy watching me die because I took his girl". He sent me all of these on direct message on instagram, thankfully I screenshot all of them because he blocked me soon after so the messages went away. He recently told my girlfriend(his ex) that he was gonna talk to his cop friends and file a report on me so my house will be searched. He lives in a completely different county, I do not sell drugs or anything like that nor live in a run down area. I am not able to pass a drug test tho, could my house be searched because 1 random person says something to law enforcement?

Edit: I am located in Mississippi.
