I don't know if she should be charged or not because I don't know all the facts, but I have to say that letting a father take his baby isn't reckless or child endangerment - in fact, if he'd called police to say she wouldn't let him have the child they wouldn't have stopped the father. And breastfeeding is not usually a valid reason for denying visitation to a father - judges make that determination all the time in custody and divorce cases.
Even if she knew he was mentally deranged she couldn't legally prevent visitation. Of course if she thought there was any real danger she could have asked for an immediate hearing - we don't know if she did or not. Does anyone have any insight into why the LE source may be claiming otherwise?
It seems to me that they had broken up and he was taking the child for a visit. The time of day for the visit shouldn't matter - infants that age aren't on any real schedule anyway.
Quote from article:
A police source says that, "the very act of allowing Mullis to leave home, early in the moring, and take the 3-month old baby with him to get his car fixed may be considered reckless and may be in violation of child endangerment law. The baby was being breast fed and should not have been seperated from his mother," the source said.
