KANSAS CITY, Mo. -- Jackson County prosecutor Michael Mansur announced Friday that because murder charges have been filed in Cass County, Jackson County will dismiss their pending case against Kylr Yust for burning Jessica Runions' car in 2016.
“The prosecutors in Jackson and Cass have agreed that we could best pursue justice by working together on this case,” said Jackson County Prosecutor Jean Peters Baker. “My office will work with Cass County in a joint commitment to the pursuit of justice for the victims in this case.”
Yust was charged with two counts of first degree murder and two counts of abandoning a corpse related to the disappearances and killings of Kara Kopetsky in 2007 and Jessica Runions in 2016.
Runions disappeared after she left a party with him in September 2016. Kopetsky vanished more than 10 years ago after she was last seen walking out of Belton High School.
At about 3:30 p.m., the Cass County Sheriff's Office said that Yust is now in its custody, his bond is $1 million cash-only.
The Jackson County Prosecutor's Office met this week with the Runions' family regarding its joint effort with Cass County to prosecute Yust and the dismissal of the pending case in Jackson County. The family wished to express their support of the joint effort and said their only concern was seeking justice for their daughter.
A decade separated the disappearances of both girls, but their remains were found near each other, just a few days apart in April 2017 when a mushroom hunter stumbled upon bones in rural Cass County.
Court papers show that the prosecutor's case started back on April 28th of 2007 -- days before Kopetsky disappeared. She told police that Yust kidnapped her after they broke up.
A judge granted her request for a restraining order on April 30th, four days before it's believed that she was killed. Kopetsky was just 17 years old when she disappeared, and was last seen leaving Belton High School in May of 2007.
Court records show that over the years investigators tried to crack Yust multiple times.
Between April of 2010 and June of 2012, multiple people who knew him called police saying Yust admitted to choking Kopetsky to death.
(Editor's note: see bottom of page for a summary of Yust's admissions to the killings)
Yust was sentenced to federal prison for drug distribution in November of 2013, and put on supervised release on September 2, 2016. That court order reads:
"You shall serve one weekend confined at a facility designated by the Bureau of Prisons. You shall report to the designated facility, as instructed by the probation officer, on Friday at 7:00 p.m. and will be released the following Sunday at 7:00 p.m. You are to pay subsistence as directed."
On September 9, 2016, Runions was reported missing a day after leaving a party with Yust where he was behaving possessive of Runions and acting aggressively towards others according to witnesses. They said Yust was drinking heavily at the party and arguing with Runions.
Police found her burned-out car on September 10. A man who was with Yust that same day told police that he drove Yust to his home in Edwards, Mo., and he was recovering from burns he received setting Runions' SUV on fire. The SUV was found in the area of 95th Street and Blue River Road. That man told police that Yust said he strangled Runions and "she was gone." Yust added that he had dragged her body into the woods.
After he left Yust, that man contacted police and told them everything Yust had said and where he was. Yust was arrested on September 11, investigators noted he had burns to his face, hands and arms, in addition to scratches on his face.
Months later on April 4th, a mushroom hunter contacted police to report that he found the remains of two people in heavy woods near Y Highway and 233rd Street. Investigators used DNA and dental records to identify the remains of Runions and Kopetsky.
