Lac-Mégantic victim identified as 4-year-old girl

The Quebec coroner's office has identified four-year-old Alyssa Charest Bégnoche as the 39th victim of the Lac-Mégantic, Que., rail disaster in July.

Alyssa's sister, Bianka, is also presumed dead.

The death of their 30-year-old mother, Talitha Coumi Bégnoche, had already been confirmed by the coroner.

Officials are still working to identify the remains of eight people.

A total of 47 were killed when a train carrying crude oil derailed and set of a series of explosions at the centre of Lac-Mégantic.
