Authorities are searching for a teenager believed to have drowned Wednesday night while trying to rescue a dog in Ottumwa. Sheriff’s deputies say 16-year-old Marco Arroyo of Ottumwa ran into the Des Moines River around 8 p.m.

He was pulled under by the current and did not resurface. The dog was able to swim back to shore. The search for the boy was called off Wednesday night because of darkness. The search resumed this morning.
