Authorities in the US state of Missouri say a 35-year cold case killing has been solved, thanks to someone who came forward with information about the crime, Report informs, citing The Associated Press.

Douglas County authorities announced Wednesday that three men have been arrested and indicted on first-degree murder, forcible rape, and first-degree kidnapping charges in the 1989 killing of 24-year-old Kelle Ann Workman. Court records show that the men do not yet have listed attorneys. All three are jailed on a $250,000 cash-only bond.

Workman was last seen cutting the grass at a rural cemetery in southwestern Missouri on June 30, 1989. Her body was found submerged in a creek more than 10 miles (16 kilometers) away a week later.

“I think we’re able to give Kelle some justice and hopefully give the family some closure, knowing that these guys are not here running around and simply getting away with it,” Douglas County Sheriff Chris Degase said at a news conference.

Douglas County Prosecuting Attorney Matthew Weatherman said the information from the person who came forward is “rock-solid.”

Asked if he was confident in the case, Weatherman said, “It’s as good as a 1989 case can ever be.”
