CHESTER COUNTY, Pa. (WHTM)-- A 12-year-old's death in Pennsylvania has led to charges against two people in what officials say is a "horrific case of child abuse."

Rendell Hoagland, 52, and Cindy Warren, 45, both of West Caln Township, were arrested and charged in the death of Malinda Hoagland, 12, the Chester County District Attorney said in a news release. Rendell was Malinda's father while Warren was Rendell's girlfriend.

“I would like to thank the Chester County Detectives, District Attorney's Office and Pennsylvania State Police for assisting the West Caln Township Police Department in making an arrest in this horrific case of child abuse,” West Caln Police Chief Curt Martinez said.

According to the DA, the duo subjected the girl to months of child abuse, by ankle cuffing her to furniture, verbally berating her, and even making her perform physical exercises when she was shackled such as squats and running in place. She was also denied meals as punishment.

“Malinda was subjected to evil and torment that no child should ever have to endure," Chester County District Attorney Christopher L. de Barrena-Sarobe said. "I am grateful to every first responder and law enforcement officer who has worked tirelessly on this case. Together we will get justice for Malinda.”

First responders were called for an unconscious 12-year-old female, located at the 200 Block of Reid Road, just before 7:30 p.m. on May 4. Rendell was the one who called 911 and when officers arrived they were alerted by medics to the child's condition, the release reads.

According to the DA, this was when everyone figured out that something was gravely wrong with Malinda, who was rushed to the hospital for emergency treatment but later died. While Malinda was at the hospital, staff noticed that she was emaciated, she weighed 50 pounds, was covered in bruises and had at least a half-dozen broken bones and her organs were failing.

During the investigation, it was discovered that Malinda was pulled out of public school in late November/early December and was shifted to a home cyber school, the DA says.

When investigators looked through the duo's cell phones, they saw Warren deleted messages between her and Rendell along with dozens of videos from their home camera system, which showed, the DA says, the child abuse.

Both Rendell and Warren are charged with attempted criminal homicide, aggravated assault, kidnapping, and other related charges.

The duo is locked up in Chester County Prison on bail set at $1 million and await a preliminary hearing scheduled for May 13.
