Ex-con charged in murder of Ohio college student

TOLEDO, Ohio -- A sheriff's investigator filed a criminal complaint Tuesday accusing an ex-convict of aggravated murder after a University of Toledo student's body was found following her disappearance last week.

James Worley, is charged in the death of 20-year-old Sierah Joughin. She was last seen July 19 riding her bike along a country road with her boyfriend, reports CBS affiliate WTOL. The two parted ways after their ride, but Joughin never made it home.

Worley was initially arrested Friday on an abduction charge in the disappearance.

Fulton County Sheriff Roy Miller did not release many details Friday into what led to the charge against Worley, other than saying, "We have enough probable cause," according to the station.

The sheriff later confirmed that the remains found in a cornfield Friday were that of Sierah Joughin.

Investigators near Toledo have been looking into the possibility of additional victims because the circumstances of Joughin's death are similar to a 1990 abduction near Toledo.

In that case, the woman was able to fight off her attacker. Worley was convicted and spent three years in prison for that crime.

Worley has rejected interview requests. His attorney declined to comment.
