 A death investigation is underway after a body was found at Lyons Park Sunday morning. Just before 7 o'clock, a woman called 911 saying a man was lying in the grass. Officers arrived and found the man, who was pronounced dead at the scene. Sock Rapids police posted on social media that Lyons Park and the splash pad were closed Sunday due to an active investigation. Officials expect it to be open today. A team from the Minnesota Bureau of Criminal Apprehension was called in to assist.
