KANSAS CITY, Kan. (AP) — A 37-year-old Kansas man has pleaded guilty to charges connected to a 1999 sexual attack and stabbing.

Thirty-seven-year-old Jibri Liu-Kinte Burnett of Olathe pleaded guilty Friday in Wyandotte County to attempted first-degree murder and rape.

Authorities say that in August 1999, an unidentified victim found repeatedly stabbed was rushed to a hospital. Doctors recovered the attacker’s semen from the victim and entered it into a federal criminal database.

Wyandotte County prosecutors say years passed before the semen sample was proven to be a genetic match to Burnett. He was arrested last May and will be sentenced next month.
