A VOP is a Violation of Probation.
Some states have recomended written guidelines for bond. Some don't. But basically all look at bond the same way.
To make a bond determination the judge looks at the personal amd criminal
history and background of the defendant, including any warrant history, the seriousness of the crime that's charged and the strength of the state's case, and the defendant's ties to the community and whether or not the defendant appears to be a flight risk. His figure is based on balancing those factors.
In your daughter's case, he sent high bail on what is not a very serious charge. That's his way of saying that he thinks she's a likely flight risk (family elsewhere in the country, presently homeles) and also that she's out of control (one arrest shortly after being given a break on the other). It also reflects the judge's expectations that probation will be done with her and that some jail time is likely.
That does't mean, however, that she will get resentenced to jail It is going to depend on what probation is going to want to do with her. And that goes back to what I said before. Probation will look at her history and background, the new case, the underlying facts of the old case, how well she got along on probation, whether she was in trouble with her probation officer before or whether her record has been exemplary and so on. And they will decide whether there's any point in letting her remain on probabion.
If probation wants to revoke, then they will recommend a period of incarceration to the judge that they feel would be appropriate. House arrest is one possibility that can be bargained for if probation wants jail.. But if she has nowhere to stay that probation would approve of, the odds of their wanting her to do some time is good.
