A Kansas City man on trial for two counts of first degree murder has testified that he didn’t kill the two women but suggested that his dead half-brother did.

Kylr Yust took the stand in his own defense Wednesday in connection to the deaths of 17-year-old Kara Kopetsky and 21-year-old Jessica Runions. Yust left a party with Runions before she disappeared in September 2016.

Kopetsky had filed a protection order against Yust in April 2007, a month before she was last seen.

Yust testified on Wednesday that he did not kill the women, and suggested that his half-brother, who died by suicide in 2018, was involved in their deaths.
