Police have released the first picture of a mum who was found dead after she allegedly killed her three children before going on the run.

Deborah Pel, 45, is considered a key suspect in the killings of her three children, a 13-year-old girl and her two brothers, aged 11 and two, at their home in Taninges, Haute-Savoie, a small commune tucked into the French Alps. The children's horrified grandparents were left to discover the bodies while visiting the property at 1pm on Tuesday afternoon.
