A judge in Knoxville has sentenced a Jonesborough man to 30 years in prison in the repeated rape and impregnation of his daughter. Marshall Dean Minckler Jr. pled guilty to two counts of child rape. Prosecutors say Minckler repeatedly molested his daughter, beginning when she was 11. She gave birth at age 13. The victim no longer lives in Tennessee and does not use her father’s surname. Her mother did not object to publicly identifying Minckler. The public defender representing Minckler told the court his client denies much of the state’s case against him, but acknowledges he fathered the child.
