The mother of two boys found dead in a car has been charged with ‘involuntary manslaughter’ after giving different versions of events to police as to how they got locked in.

The boys,aged 4 and 2,were found to have suffered heart attacks in sweltering 40C heat in Carpentras,south of France,on Monday afternoon.

Prosecutors initially reported the children had ‘allegedly locked themselves’ inside the vehicle without their mother’s knowledge.

But it has now emerged that the boys’ mother claimed to have ‘forgotten her children’ while shopping,French daily Le Parisien said,citing a police source. 

A source close to the investigation told AFP that the mother gave police several different versions of events.  

In her revised statement,the mother said the children got inside the car without her knowing,locked the doors behind them,and became trapped inside,without her knowledge.
