Emma Molemans and her three best friends were killed in Tuesday night’s coach crash in a Swiss tunnel that claimed 28 lives — 22 children and six adults. Another 24 children were injured, some of them seriously.

“I’m still waiting and hoping that someone is going to phone me and say that it’s a terrible mistake and that my little Emma is still alive,” Johan Molemans told Blick from his home in the Belgian town of Lommel.

On Thursday morning, Emma’s final letter arrived at their home, written from the Swiss resort where she and her friends were on a skiing holiday.

“Hello to all of you at home, I took the lift today, my ski instructor is super nice,” she wrote.

“We also did some walking, afterwards we slid down the slope on a plastic bag, and in the evening we sang all the songs, it’s really marvellous here.”

Molemans’ voice broke when he read out her final words, Blick reported: “I miss you so much.”

It was a shock to receive the letter in the post, he said, but it was also good to know that Emma had lived some beautiful days just before her death, he told the paper.

He was staying at home with the family’s two sons, 10 and 20 years old, while his wife went to Switzerland to bring home their daughter’s body.

Emma died beside her three best friends who were seated up front, just behind the driver.

The four 11-year-olds had been inseparable, her father recalled.

“Emma grew up with her cousin Emily. They’ve always known each other, and the quartet formed at school when they met Eline and Emma,” he said. “From that moment on, they did everything together.”

Blick carried a photo of the smiling girls tucked up in sleeping bags, side by side.

They had shared the same bedroom during the holiday and it was his daughter’s first time skiing, her father said.

The week-long Swiss skiing holiday for some schoolchildren had been a local tradition for 40 years, he explained.

Emma’s 10-year-old brother, meanwhile, was still trying to comfort him, said Molemans, telling him that his sister would surely wake up again.
