JACKSON, Wyo. (AP) — Attorneys for a 42-year-old Wyoming man who has pleaded guilty in the killing of his pregnant ex-girlfriend have withdrawn a request to change his plea.

Erik Ohlson, of Jackson, had pleaded guilty in February to murder and manslaughter in the killing Jennifer Nalley at her Teton Valley, Idaho, cabin. But last week, his attorneys filed a motion to withdraw that guilty plea.

A judge was set to hear arguments on the motion Thursday but on Wednesday night Ohlson's attorneys filed to withdraw the motion.

Prosecutor Billie Siddoway says the court will now proceed to Ohlson's previously scheduled May 9 sentencing.

Ohlson has been in custody in the Madison County Jail in Idaho since his July 2016 arrest.
