Thanks everyone for your sentiments and ideas. The one thing that makes me think they weren't casing it for a later return was I would think those type of criminals would want to leave no trace of their being there.
Taking medications and a cell phone certainly moves me to action I may well not have taken before.
Plus, there is only one company in the area that can activate that phone so I need to get my information, receipts and serial numbers to AT&T. Maybe they can notify me or the police if someone comes in with a stolen phone.
