OLATHE, Kan. (AP) — A 31-year-old Johnson County man will serve at least 40 years in prison for sexually molesting an 8-year-old girl.

Robert Donovan Burton was sentenced Tuesday to life in prison with no chance of parole for 40 years for abusing the girl at an Olathe home in late 2012 and early 2013.

The Kansas City Star reports it was Burton’s second conviction for a sex crime involving a child. In 2005, he pleaded guilty in Johnson County District Court to attempted rape of a child younger than 14. In that case, his 12-year-old victim later gave birth to a child fathered by Burton.

The girl in the latest case reported to authorities that Burton molested her after showing her pornographic videos on his cellphone.
