The arrest comes after Washington State Patrol issued an Amber Alert for his four-year-old daughter Grace Susmilch around 10:45 a.m. Saturday. She was found safe just before 2 a.m. Sunday in Pasco.

The Benton County Prosecutor's Office sought an arrest warrant for Susmilch early Tuesday. A judge approved the warrant, and after he surrendered himself, Susmilch was booked into the Benton County Jail on that warrant, as well as a Department of Corrections warrant.
