BOBIGNY (AFP) - A woman whose 10-year-old son was found dead in a suitcase was on Sunday (Jan 30) charged with his murder, French prosecutors said on Sunday.

The 33-year-old woman had failed to "explain the facts" and had been "evasive" during questioning, local prosecutor Laureline Peyrefitte said in a statement.

A post-mortem showed the boy was "killed with a bladed weapon, like a knife" and had "received multiple fatal blows to the neck and chest".

Investigators say the boy was likely killed last Wednesday.

His mother is then believed to have moved the body in a suitcase in an attempt to dispose of it before returning to the family home in Ferrieres-en-Brie, to the east of Paris, to clean, the statement said.

The authorities later found blood stains at the property.

The body of a child inside a suitcase was found last Thursday morning 100m from where he lived.

The woman was later arrested at the home of her sister 30km away. She was in possession of a bloodied knife.
