DES MOINES — A man’s body was found Saturday in the Des Moines River near a park in Des Moines.

A fisherman and a cyclist riding on a riverside trail both spotted the body near Riverview Park on Saturday afternoon and called police, spokesman Sgt. Paul Parizek said.

A Polk County medical examiner will conduct an autopsy to determine the cause of the man’s death and identify him. Parizek said investigators believe the body may be a man who jumped into the river at Prospect Park on March 17 after fleeing police.

In that March 17th incident, a man yelled at officers who were in the park on an unrelated matter and then hopped in a vehicle and drove erratically before getting out of the car and jumping into the river.

Authorities searched the river for that man on March 18 and 25 but did not find him.
