Since I was almost certain that Sammy was hiding somewhere around the fridge or stove, I put a lot of plastic grocery bags around that area. Last night around 11pm I heard a loud KRINKLE, KRINKLE, looked over and saw Sammy sliding around. Unfortunately I walked over there too soon and startled him so he skedaddled back under the fridge. I was disappointed, of course, but at least now I know that he's a)alive and b)still in my condo. Hopefully I'll be able to capture him sometime this weekend.
