To make a long story short, on the evening of July 12 2015 I was in a Chinese restaurant. It's called Red Palace and it's located at Tanglewood mall in Roanoke Virginia for those searching! I left a iPhone 5s at my table because I was very careless and I needed to get to a meeting. The next day I went back to retrieve my phone. I spoke the owner, a young guy, and he said he thinks he saw the phone however he is not sure. After consulting with the staff, he said the phone was not there and they did not have it. I had an app on my phone that can detect my iPhone's location, it said twice it was at their address. I went back to consult again, this is back in July- with the police. The police took statements but didn't do anything. They said I can't prove they have my iPhone. Now it's been a long time, the phone didn't have a passcode as it was just a business phone I used for making business calls. I can't trace it anymore because someone either deleted the app or manipulated it. I recently went back to the Chinese restaurant with a friend. I saw one of the staff with an iPhone 5s that looked so much like mine. I think it must have been mine. I demanded the staff show me the phone. They were not willing. The manager asked me to quit accusing his store of being full of thieves and to delete my Facebook posts about it. He said he would sue me for slander. I deleted my Facebook posts but I still have a gut feeling they have my iPhone 5s… Is there anything I can do?
