[ma] My Deceased Uncle’s Landlord And Management Company Went Through His Apartments Belongings Before Letting Me In. How Do I Know Nothing Was Taken?

Hello, my uncle recently committed suicide in his apartment in MA. My mom and I went over after not hearing from him for a day, as we spoke every day. We found him with a gunshot wound to the head and it was ruled suicide, everything has settled down and we wanted to clean out his place. After providing the court papers to show proof of executorship, the complex claimed it wasn’t the proper type. We asked if we could go in to see if his safety deposit box with important info in there. After relentlessly begging, they agreed only if they could videotape us while finding the box. To our surprise, they organized and moved everything into the kitchen. Brand new bedroom furniture is gone that we bought together, and they claim they threw it away. This doesn’t seem right? How do me and my mother know if they stole anything? He was an avid Rolex collector, and I saw none of that during my short, supervised visit. It’s hell trying to get back in to clean it out, and now we must wait longer. We have a lawyer, and he’s a bit confused but not alarmed like us. They didn’t even notify us to let us know they’d be cleaning it up? Something doesn’t seem right, is this legal? I smell hanky panky to be honest
