Will a ball python eat a mouse that is already dead? Not like F/T but if they get out and find a dead mouse, is there a chance that they will eat it?

I already have a thread about Lilly getting out, but I needed this to pop up new...I'm really worried about her. I just remembered that my mom had a really bad mouse problem a few months ago. For a long time she was just catching them and dropping them in a field several miles away (she doesn't want mice in her house, but she doesn't want to kill them either) but eventually there were so many that she had to posion them I have been tearing the house apart looking for Lilly, and when I got into the water heater (it's inside, in a room that Lilly could have gotten to) I found a dead mouse. I'm scared to death she is going to eat something that is going to make her sick. I have thrown away anything that I have found, but I can't find everything (obviously since I can't find her ) Anyways, how much of a chance is there that she is going to eat this stuff?

She didn't get fed last week or this week, and I know they can go for a while without food, but she has a very good appitite, and has slammed the mice I have given her when I fed her the last few times. I hope I'm just worrying too much, but it scares me that she will get really sick and die.

Sorry for bugging everyone over and over again, but I'm really worried about her...
