Yes, she basically arranged for her own daughter to be kidnapped. So, she should be charged as an accessory along with the rest of the gang.
Based upon various investigative reports I have seen, being kidnapped is the least of her worries. Many of these girls are forced to use drugs (with the intent to get them addicted), then used as sex workers, they are then bought/sold to various individuals/groups/gangs and are forced into a life of prostitution.
So, when Mom finally comes up with the cash, she'll likely get a drug-addicted, pregnant and damaged daughter with an in-depth life experience in the field of prostitution. Ain't illegal smuggling grand?
