MARTINEZ -- A serial child molester was sentenced to 160 years to life in prison Friday for molesting a 4-year-old girl in Martinez in 2012.

Oakland resident Ronald Heartsill, 58, was convicted by jury on Oct. 1 of two counts felony counts of child molestation. His punishment was compounded by his prior convictions for molesting two boys in San Pablo in 1983, and for molesting a girl in Clayton in 1990.

"I don't have nightmares anymore because he (is getting prison) time again," said the victim in the Clayton molestation, who was 9 when Heartsill assaulted her. "He hurt me really badly."

Heartsill also has a prior misdemeanor child molestation conviction for an incident involving a 16-year-old boy in Martinez in 2000. He did not make a statement at sentencing.
