A Charles County jury convicted a 72-year-old man on incest and other charges in connection with sexual abuse that he committed from 1971 to 1979.
The victim was between seven and 15 years old at the time of the abuse.
The jury convicted Donald Richard Twigg on charges of incest, child sexual abuse and other crimes. He is accused of sexually assaulting his daughter for almost a decade in the 1970s.
During the August trial, the victim testified that Twigg molested and sexually assaulted her. In the trial, a 2010 telephone call between the victim and Twigg was played in which Twigg essentially admitted to having sex with his daughter, according to the Charles County State's Attorney.
The phone call was being recorded by Charles County police.
During the trial, Twigg testified on his behalf and denied the accusation, according to the state's attorney.
"Sexual assault cases - especially those involving family members - are the most under-reported crimes in our society," said Charles County State's Attorney Anthony Covington. "I hope that other victim's out there will hear of this jury's verdict and will be encouraged to come forward to hold their abusers accountable and, just as importantly, free themselves of the emotional and mental prison that their abusers created for them."
