(AP) — Authorities have arrested a rural central Nebraska man for the shooting death of a Grand Island trial attorney outside his law office.

58-year-old Michael L. Petersen, of Glenvil, faces first-degree murder and weapons charges. Petersen was arrested near Hastings Thursday evening. Police say he was armed but offered no resistance.

Petersen is accused of killing 52-year-old Todd Elsbernd on Wednesday. Authorities say Elsbernd was likely targeted.

Elsbernd is listed in court records as having represented a man named Michael L. Petersen in a divorce case involving a woman named Nancy Petersen.

A woman named Nancy Petersen was found shot to death Thursday in rural Buffalo County. Authorities say they are investigating whether the shootings are connected.

Petersen is expected to appear in court Friday.
