Defamation lawyers typically want $5,000 just to begin work, so unless you sustained a significant monetary loss, you could end up paying more than you might recover. Call the police again if more harassment.
Your post is a bit confusing. If it is the other "person/people" living in the complex that was/were the one(s) who "slandered" and "defamed" you, then there is no defamation action against the property management. The only ones that you could arguably pursue such a claim againt are the other tenants (?), who presumably are the ones who spoke ill of you. That is a wholely separate issue as to whether what was said would be found to be "defamatory" under the law. There is also the practical matter as to whether those other tenants have sufficient personal assets to make if worth your spending of substantial money and time pursuing legal action against them. It is not clear what "drug test" you feel management should have taken, but it is hilghly doubtful that such failure could be found to cause management to be legallly liable to you in some manner. As for pursuing legal action because you want a "formal apology", it can be said in a most general fashion that lawsuits commenced because of "principal" usually cost the party bringing the suit more money than will be recovered - interpreted to mean: a waste of time and money.
