On what basis will the RO remain in effect, though? There's no evidence she harmed Kyron. If there was evidence she implemented a murder-for-hire, she would've been arrested. The very fact that LE needed a sting operation tells me they didn't have overwhelming evidence against her in the first place, and as we all know, she didn't incriminate herself in the sting operation.
The RO is tied to the murder-for-hire accusation, but ultimately, that's all it is, IMHO. There's no proof. I don't believe the RO will remain in effect indefinitely based solely on the word of lawn boy. If it was that easy, every disgruntled, non-custodial parent in America would be placing ads for a lawn boy to come up with some cockamamie story about their ex- husband or wife.
It doesn't matter what LE believes is true, it matters what they can prove is true. If LE can't prove that Terri harmed Kyron or that she wanted to hire some lawn boy to off her husband, then there is no legal reason to keep her from her baby.
