i swear. >> darly routier was charged with two counts of capital murder. convicted, she could face the death penalty. >> one thing that investigators found very suspicious was a very odd comment that darly made on the 911 tape regarding fingerprints. >> i picked it up. >> it's okay. >> she's got two children dying in front of her. boy, that thing that comes to her mind is finger prints. >> common sense tells me no mother would ever make a statement like that. the only inference we could draw was she was setting up why you're not going to find an intruder's finger print on there. >> when she said don't touch anything it clicked in my head, you know, oh, my gosh,dee. >> they left the knife. >> there's a knife, don't touch anything. >> i already touched it and picked it up. >> the strongest evidence of innocence are the photographs of darly. >> in all the murder cases i've tried, i've never seen a self-inflicted wound in the neck like that. i mean, just a fraction of a millimeter more, she would have bled to death. >> everyone agrees that darly had wounds. bu
