(CNN)Police in Detroit made a gruesome discovery Tuesday.
A bailiff performing an eviction on a home on the east side of Detroit called 911 after discovering the body of a child inside a freezer. While investigating the body of a girl, authorities found a boy’s body, according to a release from the Detroit Police Department.
Both bodies were inside a plastic bag, Detroit Police Chief James Craig said.
The mother of the children was apprehended at a separate location, Officer Jennifer Moreno said. Police have not yet released her name, but are questioning her.
The names of the children have not been released, but Craig said the boy was approximately 11 years old and the girl was approximately 14.
There were two older children living in the home. They have been placed in protective custody, according to Craig.
The chief said it’s too early in the investigation to determine what happened.
“It’s unknown what factors were involved in this,” he said.
Moreno said the department is asking for the public’s help to come forward with any information pertaining to the crime.
