New details, prior to the Kosovo couple's murder, had occurred in a fight at the apartment.

French media write that the police had gone to intervene after a disagreement between a brother and a sister, but it does not become known whether the deceased couple's children or some relative of their own.

This family for three years was staying in the residential block in the Plateau de la Justice area, and never were neighbors any complaints to them.

So far the circumstances of the couple who had been found in the bathroom by their children are unknown. But they're allegedly stabbed.

Police are investigating the case until it is said that the children's testimony is essential to understanding what really happened. So far, no details have been made white by the initial findings of investigators.
