My ball python has been missing for about a month and a half now. I've looked every where.?

Last time I found him in the closet balled up under stuff. Checked there again, no luck. I think he's under the sink/ cabinet area but I'm scared to look I need a flashlight, 4 more bodies, more mice. I wasted 2 of them. I place the mice on a newspaper under the cabinet for a loooooong time....NO LUCK!!! Could it have went down the toilet??? I'm sadden :( just my Charlie went away. What should I do next?? He didn't come get the bait. Could he be dead???
