 An investigation is still ongoing, and authorities hope to have a timeline sooner rather than later. And Mills County authorities report a pair of warrant arrests and separate incidents earlier this week. The Mills County Sheriff's Office says Glenn Eugene Gallagher of Omaha was arrested at around 9.15 p.m. Wednesday on a warrant for violation of probation. Authorities say the arrest occurred at the Mills County Jail. Gallagher was held on a $2,000 bond.
