Ask her to return the pic. Say please return my pic and your brother's belongings. Don't say she stole anything.
Hello, I want to get a 250 dollar picture back that my daughter stole from me, and my son was kicked out of her place and kept some of his things and won't give them back, how do we get our things back ?
Do you have any legal proof of ownership? If so I suggest to take it straight to small claims court. If you win, she will be court ordered to return everything and you can request to have an officer assist you.
When you have a disagreement or conflict with a family member, it can turn ugly fast. You could take your daughter to small claims court, as others have suggested. The end result is that you'd have to prove the items are yours, the judge could rule in your favor and order the item(s) returned, she would refuse to return them and you're back where you started.
It doesn't sound like your daughter is very respectful to either you or your son.
If this were me, I would try for a face to face talk with her and respectfully ASK for the items be returned. Don't engage in any type of argument. Just ASK for the return of your belongings.
If that fails and she refuses, be the bigger person and walk away from this train wreck. She doesn't value the relationship with you or she wouldn't have stolen the items in question.
If your son still has a key, go in when she isn't home and get it. Unless he was on a lease he has no legal rights.
Take her to court .. And if you can convince a judge that these articles belong to both you and your son, then the judge will order her to return them.
.. Or call the police and charge her with theft.
