OMAHA, Neb. (AP) — Authorities investigating the deaths of a Nebraska woman and her 10-year-old son say they are not looking for an “outside” killer or at-large suspect. Council Bluffs, Iowa, Police Sgt. Dave Dawson says investigators “do not suspect any outside foul play” in the deaths of 41-year-old Charlotte Schilling and her son, Owen Schilling, of Plattsmouth. Their bodies were discovered Sunday evening in a wooded area of a state park near Council Bluffs in western Iowa, about 20 miles north of Plattsmouth, but were not identified until Tuesday. The pair had been missing since May 10, when Schilling checked Owen out of his elementary school. Police found Schilling’s vehicle the next day at the park. Dawson says he expects police to release how they died later this week.
