Mark Bridger, 47, had been convicted earlier in the day of murder, abduction and unlawfully disposing of and concealing the body of April Jones, The Guardian reported.
In sentencing Bridger, Justice Griffith Williams described him as "a pathological and glib liar."
Prosecutors had charged that Bridger abducted the girl Oct. 1 while she rode her bicycle near her home in Machynlleth. 1. He killed her before burying or disposing of her body.
Her body has never been recovered but Bridger is reported to have told a priest while in prison awaiting trial that he had thrown the body into a river.
Police say the girl was killed in Bridger's home and her body cut up and disposed of in several places.
