I'm not buying this "Mom was weak" business.
She was joining the armed forces for gosh sakes.
I truly believe this woman is as sick as the demon on trial. It seems apparent to me that many women have children to use for their own purposes. It may be to get back at a boyfriend, (child support for eighteen years), to collect welfare (professional baby maker... unfortunately I know too many of these), or to live through vicariously. Note, all of those things are bad enough... but usually there is some degree of caring, however misguided. Those women are weak... women like Teghan's mom (and Hailey Dunn's mom, IMO) use their little girls to entice men, and have no qualms about their child being sexually abused if it means boyfriend stays.
I hope this demon's accomplice is treated as such -- a criminal, not a poor oblivious woman. Unless she is mentally disabled, she darn well knew.
