On Thursday evening hundreds of people visited St Laurence Church, in Measham, to pay their respects to Kayleigh.
Reverend Linda Cox, from the church, said: "It was a very sombre atmosphere in there, but it was also a very supporting and loving atmosphere for each other and particularly for Kayleigh's family."
Eddie Green, head teacher of Ashby School where Kayleigh was a pupil, paid tribute to the teenager describing her as a "fun-loving" girl.
He said: "Our thoughts are with the family of Kayleigh Haywood at this difficult time.
"[Kayleigh] had started Year 11 with a real determination to be successful. It would appear that this opportunity has sadly been taken away from her.
