The search for a missing three-year-old girl in Bryan, Texas, has taken a dark turn as investigators found human remains near her home.

According to an ABC 13 report, Rayven Shields was reported missing by Child Protective Services on Monday, after a case worker visit to her home raised concerns. Rayven was not seen at the visit, and her mother reportedly gave conflicting reports about the girl’s whereabouts.

The mother was arrested on Wednesday for interfering with child custody.

“Her mother was not cooperative and told inconsistent stories about where Rayven was,” Bryan Police Chief Eric Buske told the news station.

Police brought in a cadaver dog to search the property on Friday, and investigators found human remains on the same day.

“Buried in the garden, we located decomposed remains that are consistent with the size of a young child,” Chief Buske said.

He also said that police believe the girl may have been missing long before the Child Protective Services report, and the investigators are not certain of when she was last seen.

“We don’t know the last time she was seen but we’re thinking it’s sometime in the middle of June,” the police chief said.

The remains have not yet been positively identified, and Rayven’s mother has not been charged with murder, though investigators reportedly believe someone close to the child is responsible for her death.
