"Their hip bones were protruding from the pelvic area and bones along the spine were pushing through the skin of their back with the beginning stages of an open sore," Hester said. "Medical evaluations all confirmed this condition was a direct result of malnutrition and required a feeding tube to try and gradually bring the child back to the appropriate level of nutrition for their age."
Hester said Kirschenhofer is a stay-at-home mom and was responsible for the children in the household, TC News reports.
Hester called this case "some of the most appalling examples of child neglect that I have heard in my 26 years in law enforcement."
The Florida Department of Children and Families removed the children from the home on Feb. 22, according to WPTV-TV, after they received an anonymous complaint on Feb. 10.
The three teenagers are with their mother, who reportedly did not know about the alleged abuse. WPTV reports the two other kids, ages 6 and 9, are living with other relatives.
Oscar Torres and Brittany Kirschenhofer were both charged with three counts of aggravated child abuse, and were held in the St. Lucie County Jail on $90,000 bond each.
