I know absolutely nothing about this story, but there’s no excuse for these yahoos congregating at the house and causing a public disturbance.
It doesn’t matter whether the woman is guilty or not. You’ve got better things to do than stand out there and throw rocks and pennies at her parents’ house. Go home.
Her father says he’ll be filing charges against the trespassers. I hope he does and I hope they pay fines and do some time in the county lockup. Harrassing these people does absolutely nothing to solve this case. The harassers ought to be ashamed of themselves and they ought to pay a price.
Personally I’d have been out there with a shotgun, not a ball bat and a garden hose.
