The man believed to be behind the disappearance and death of Sierah Joughin, the 20-year-old Ohio college whose remains police believe they found last Friday, was charged with aggravated murder Tuesday on top of the abduction charge he received last Friday, PEOPLE confirms.
James Dean Worley, 57, of Delta, was charged with abduction after authorities discovered a body they believe is that of the missing University of Toledo student. Police have not positively identified the body yet, pending DNA and fingerprint tests, and the Fulton County Coroner’s Office would not yet confirm the body was Joughin’s.
At a news conference Friday, Sheriff Roy Miller said there was no known connection between Worley and Joughin, but Worley previously pleaded guilty to abduction in a 1990 case also involving a female cyclist, according to court records obtained by PEOPLE.
According to the documents, Worley was driving a flat-bed truck when he hit the cyclist. He then stopped the truck and, after asking the victim if she was okay, struck her on the head with an unknown object and said to her, “Do what I say or I’ll kill you,” according to the documents.

Worley then forced the victim into his truck and handcuffed her right wrist, but she was able to escape, according to the documents. A passing motorcyclist who noticed the confrontation allowed the victim to climb onto his motorcycle and drove her to safety.
Worley was released from prison on parole in 1993, according to NBC.
Court officials tell PEOPLE that Worley is being held at the Corrections Center of Northwest Ohio without bond. He has not entered a plea for either charge. His attorney, John Shaffer, did not immediately return PEOPLE’s request for comment.
Joughin was reported missing by her family last Tuesday night, local authorities have said, just hours after she didn’t return from riding her bicycle with boyfriend Josh Kolasinski, who was riding a motorcycle.
(The pair parted amicably, authorities have said.)
Joughin’s bike was later found in a cornfield.
The Fulton County Coroners Office has not released Joughin’s cause of death.
A GoFundMe page has been set up to help the family.
