Texas law enforcement officials have arrested the mother of the children abandoned with the skeletal remains of their dead sibling.
Authorities also took her boyfriend into custody just two days after the three children were found abandoned inside the squalid Houston-area apartment after months of being alone with their dead brother's corpse.
What are the details?
According to a Tuesday report from the Daily Mail, authorities arrested 35-year-old Gloria K. Williams and 31-year-old Brian W. Coulter in connection with the abandonment and alleged murder.
Authorities charged Williams with injury to a child by omission, failure to provide medical care, and failure to provide adequate supervision. Coulter was charged with murder in connection with the 8-year-old child's death.
A spokesperson for the Harris County Medical Examiner's Office said that the deceased 8-year-old child suffered multiple blunt force injuries at least one year ago.
Williams' 15-year-old son, who was caring for two younger brothers — ages 10 and 7 — called 911 on Sunday, prompting the welfare check that revealed the grisly findings. Just before calling emergency services, the 15-year-old reportedly texted his mother and said he could not take living this way any longer.
According to Harris County Sheriff Ed Gonzalez, the three siblings were left to fend for themselves for months at a time and relied on food donations from concerned neighbors and more.
"It appears they were basically fending for each other," he told reporters. "The older sibling was doing the best he could to take care of the others."
He added, "Very horrific situation here, very tragic. I've been in this business for a long time and I've never heard of a scenario like this, it really caught me by surprise."
"We are trying to identify next of kin to determine exactly what happened and how we got to this point," Gonzalez continued. "We're going to make sure we conduct a thorough follow-up investigation."
All three siblings were taken to a local hospital for treatment and were determined to be suffering from malnourishment and other injuries, including broken bones in the 7-year-old child's face.
Child Protective Services has also launched an investigation into the incident.
In a statement, the agency said, "To ensure the safety of the children, the Department of Family and Protective Services is seeking emergency custody of the three boys. Child Protective Services does have history with the family, but there was no active CPS investigation at the time the children were discovered alone in their apartment."
