Confirmation of the appeal was distressing for the Longley family, but not unexpected.
"I'm not surprised given Turner's nature," he said.
Turner showed no emotion over Emily's death. He had bragged of how he would move to Spain once he escaped conviction.
Mark Longley said there was no guarantee Turner's appeal would make it to court as there would first be a hearing to determine whether the appeal should proceed.
Longley said the prosecution case had been robust and the legal team so thorough in its work that even if an appeal did proceed he was confident that Turner would remain exactly where he was - in prison.
Meanwhile, Turner's parents Leigh, 54, and Anita, 51, will be sentenced at the end of next week for perverting the course of justice in trying to cover up for their son.
Mark Longley said he was looking forward to the day when all the expected appeals and sentencing were behind them. Then he and his family could get on with life and grieving for Emily without thinking of Turner or his family - until the killer was up for parole in 16 years' time.
