A 44-year-old Fairburn man was sentenced Tuesday to 20 years in prison to be followed by 20 years probation for repeatedly molesting his daughter.

The man was convicted of two counts of child molestation and one count of cruelty to children in the first degree for events involving his daughter when he lived in Cobb County. The Cobb County jury, however, could not agree on a verdict on the remaining six counts of rape and incest.

The Atlanta Journal-Constitution is not naming the man because it could identify the daughter. The AJC has a policy to not identify sexual assault victims.

The man had not been a part of his daughter’s life until she was 10, according to District Attorney Vic Reynolds. She is now 16.

At the time of the crimes, 2008 to 2013, the father lived in a Cobb County apartment that was furnished only with a mattress on the living room floor, which is where he slept with his daughter.

He would give her wine and sometimes marijuana and that was how she “knew it was going to happen,” the daughter testified.

“Young girls look to their fathers to be their ultimate protectors,” Cobb Superior Court Judge Henry Thompson said during the sentencing. “By molesting your daughter, you not only committed a crime, but you committed the ultimate betrayal of that trust.”
