RIVERDALE — A paternity test linked an Oregon man to an 18-year-old Riverdale girl’s 3-year-old child, leading to his arrest on a first-degree felony rape charge.

Authorities booked Shaun Michael Fornoff, 33, into the Weber County Jail in Ogden on Thursday after he was picked up on a bench warrant.

The Weber County Attorney’s Office had filed charges of rape and forcible sexual abuse, a second-degree felony, against Fornoff on Feb. 25.

A Riverdale Police Department warrant said Fornoff was investigated beginning in January 2018 after the girl contacted the Utah Division of Child and Family Services.

The teenager said she did not report the alleged offense in 2015 because it was too difficult for her. She was 14 at the time. But she decided to come forward in 2018 and said Fornoff had raped her while staying with her family.

Authorities collected DNA from the girl and her son and Riverdale police obtained a warrant to collect Fornoff’s DNA.

Weber-Morgan Narcotics Strike Force agents located Fornoff during an investigation into drug dealing and his DNA was taken. The affidavit said Fornoff invoked his Miranda rights and he was not questioned about the alleged rape at the time.

A genetics lab reported there was a 99.99 percent chance that Fornoff was the child’s father. But by that time he had moved to Oregon after receiving a suspended sentence in the drug case and being put on three years’ probation.

It was not known how local police found Fornoff on Thursday.

A judge ordered Fornoff held in lieu of $100,000 bail. No court appearance was scheduled for him as of Friday and he did not yet have an attorney of record in the sexual assault case.
