A 38-year-old man drown while swimming in the St. Clair River along the Thomas Edison Parkway in Port Huron on the Fourth of July, police say.
Port Huron Police say they were called on the report of a missing swimmer around 5:50 p.m.
Witnesses reported seeing the man yelling for help after waves from passing boats seemed to overtake him.
Police say the man, identified as Kenneth James Johnson, was found underwater shortly after arrival of emergency crews and resuscitation attempts were unsuccessful. Johnson was pronounced dead at the hospital.
"This tragedy is a very unfortunate reminder of the dangers associated with swimming in the St. Clair River," read a statement from the Port Huron Police Department.
