It was just after 12.30pm.“They seemed happy. The children had balloons and he bought them sweets. There didn’t appear to be anything wrong. He also bought a baguette.“We see a lot of him here. He is friendly with my staff and always talks to the servers.“He has always come across as a nice man, but he changes when he drinks. He’s not very good with alcohol.“It was obvious he was a foreigner. He spoke French well, but with an accent, we used to joke that he must be from Canada.“I know hundreds of people, everybody comes here to buy their bread, but I remember Mr Stevenson because of his accent.“This tragic incident has shocked everybody. He always appeared to be a good dad and a caring father.”Stevenson has been living in France for 10 years.He appeared in handcuffs before a French judge on Monday after being driven into Lyon's Tribunal de Grand Instances complex with his head hidden under a blanket.His wife spoke to prosecutors on Sunday, providing them with their details of her troubled relationship with her ex-husband.Investigators were particularly keen to know who gave the father legal authority to look after the children unsupervised.DisturbingRest In Peace Mathew & Carla
