A registered sex offender pleaded not guilty in Laramie County District Court Thursday to six charges involving child molestation.

Paul D. Hatcher, 58, is accused of sexually abusing his son in 2014 and his nephew between June and July of 2015, when the boys were around 6 years old.

The incidents are alleged to have occurred at Hatcher's trailer home in Laramie County.

Charging documents allege Hatcher placed his penis on his nephew's buttocks and in his mouth, and placed his mouth on his nephew's penis. He's also alleged to have touched his son's genital area.

Hatcher has been charged with three first-degree and three second-degree counts of sexual abuse of a minor. If convicted, he could face 75 to 210 years in prison.

Hatcher remains in the Laramie County jail on a $15,000 cash bond awaiting trial.
