TOPEKA, Kan. (AP) — Attorneys for a Kansas man convicted of killing a 14-year-old girl in 1999 have asked the court to vacate his first-degree murder conviction.

The Topeka Capital-Journal reports  that lawyers for Floyd S. Bledsoe filed a motion Tuesday in Jefferson County to vacate Bledsoe’s first-degree murder conviction in the 1999 death of of Zetta Arfmann.

Bledsoe’s lawyers are members of the Midwest Innocence Project and are working the University of Kansas School of Law. They’ve asked the judge to release Bledsoe based on DNA evidence they say shows that two other men had contact with Arfmann’s body. Results of that DNA test became available earlier this year.

Bledsoe was sentenced to life in prison in 2000 and briefly released in 2008 before an appeals court reinstated his conviction.
