SPARTA, Wis — Bail was set at $2,500 for a woman accused of child abuse and squalid living quarters near Warrens in northern Monroe County. Casandra Lamb, age 22, was arrested Friday after her 6-year-old and 5-year-old children were found abandoned and wandering lost in the McMullen Park campground near Warrens. They had been living in a camper. County Judge Mark Goodman scheduled a further hearing in July.
