KANSAS CITY, Kan. (AP) — A woman has been arrested in the 26-year-old unsolved killing of another woman in Kansas City, Kansas.

Kansas City, Kansas, police said in a news release that the U.S. Marshals Service took the 48-year-old woman into custody Wednesday in Clay County, Missouri. She is being held on a $1 million bond in the killing of Sarah DeLeon. The body of the stabbed 19-year-old was found by railroad tracks in 1989.

Police investigators said in May that they believe there is a link between DeLeon’s killing, the unsolved 1994 slaying of Diana Marie Ault in Independence, Missouri, and an abduction in 1987. Investigators didn’t say then why they believe the cases are connected.

New DNA collection and testing technology prompted police to reopen the DeLeon case in July 2014.
