CEDAR RAPIDS, Iowa (AP) — Police have arrested a 17-year-old boy charged in the slayings of his grandparents in their home in Manchester. Larry Hedlund of the Iowa Division of Criminal Investigation says police captured Isaiah Sweet on Monday night in a wooded area of Cedar Rapids after a short chase.

PLATTSMOUTH, Neb. (AP) — Authorities are treating the case of a missing Nebraska woman and her 11-year-old son as a kidnapping but they say there’s no evidence of a crime. Charlotte and Owen Schilling were last seen Thursday morning in the Plattsmouth area, when she checked her son out of elementary school. They haven’t responded to cellphone calls from relatives. Schilling’s vehicle was found Friday near Lake Manawa near Council Bluffs, Iowa. Her cellphone and wallet were in the car. Police say the two were spotted at a Kohl’s department store in Council Bluffs before her car was found. Investigators say they’re proceeding as if the boy was kidnapped, but they don’t believe anyone is in danger and the mother doesn’t face any charges.
