Funeral services are Thursday for a Minnesota father who drowned in Iowa over the weekend.

31-year-old Anthony Boyenga of Ellsworth was swimming with his children at a campground near Rock Valley late Saturday afternoon when he went under and never resurfaced. It’s believed he suffered a sudden heart attack. A dive team recovered Boyenga about an hour later. He died at the scene. Rescue efforts were hampered by poor water clarity making visibility near zero. A GoFundMe page has been set up for Boyenga’s wife and five young children, including triplets.
