Old roommate won't give me my stuff?

I recently moved out of my ex's parents house, and when I did I left behind all my stuff. When I went back to get it I was only given a percentage of it back. They stole my iphone, coach wallet, clothes, etc. What can I do?

Can I go to his moms work and watch the cameras to see if she has my stuff if I'm able to file charges?

Also, Before I got my own place after I left there it happened to me again, but this time I was given back a percentage of my stuff by the mother's son who keeps claiming it was all there. What can I do?

I was implying if I filed charges could I watch them, but I think I'm better off going and asking around to see if they've been seen with my stuff.

I forgot to add in my posts what could I do if they pawned any of it.

I have receipts for the more expensive items, and all kinds of pictures.

Your roommate's mother's work is not going to let you watch their security cameras unless you're working there as a guard. Do you have proof you owned these items? You may be able to contact the police and report it as theft.

What makes you think their workplace is going to cater to you for watching security videos? They are running a business, they have better things to do then play kiddie games like this.

You can prove you had those things and he took them. No possible way his mom's work lets you view their security footage. No chance.

What you can do is take your stuff with you when you move out of somewhere. Never leave anything behind. You would have thought you'd learn the lesson the first time.
