Authorities on Monday found the body of an 11-year-old boy who is believed to have drowned while swimming in a southern Minnesota river.

Denilson Fidel Funes De Leon of Madelia was swimming with friends in the Blue Earth River at Rapidan Dam County Park just before 6 p.m. Saturday when the current pulled him into deeper water, according to the Blue Earth County Sheriff’s Office.

He was found midday Monday about a mile from where he was last seen.
