OMAHA, Neb. (AP) — A 36-year-old man convicted of a hate crime in connection with an assault on a Marine in downtown Omaha didn’t show up to his sentencing hearing.

An arrest warrant was issued Wednesday after Missouri-native Gregory Duncan didn’t appear for his scheduled sentencing on a third-degree assault conviction. He was charged with punching Ryan Langenegger in the face after using derogatory names regarding the sexual orientation of Langenegger’ friends.

Duncan’s attorney says his client hadn’t informed him that he wouldn’t show up to his sentencing.

Jurors found Duncan guilty in February. During his trial, Duncan’s attorney accused his client’s friends of making the derogatory slurs. But prosecutors argued that Duncan had no other reason to punch Langenegger, who they say was peacefully defending his friends.
