While I'm sure she's more than "1.5 years in prison" complicit in Harmony's murder, this plea hinges on her testifying against the husband. If that's the difference between him going away for life for murder (which was going to be nearly impossible to prove without her cooperation) and him catching a much shorter sentence for "welfare fraud" or some other consolation prize, I'll take it. Plus it's a suspended 10+ year sentence, so if she fucks up after release, it's back to prison she goes.
