French prosecutors have opened a murder investigation after the remains of five infants were discovered inside a couple’s home in France. According to the available report, the discovery was made by the partner, prompting authorities to begin a criminal inquiry.

Investigators said the remains included the skeletal remains of four infants and the decomposed body of a newborn. The case has drawn significant attention because of the number of bodies found and the serious nature of the allegations now under review.

At this stage, officials appear to be focused on establishing the circumstances surrounding the deaths and how the remains came to be kept at the property. The limited information released so far does not clarify when the infants died or whether any charges have been filed.

The investigation is expected to continue as prosecutors and forensic specialists examine the evidence. More details are likely to emerge as French authorities work to determine what happened in the home.
