Indiana conservation officers are investigating the drowning as the family urges others to use caution in Lake Michigan. A Northwest Indiana family is mourning the loss of their 22-year-old son after he drowned while swimming in Lake Michigan at Marquette Park Beach. They were supposed to have the whole family day when they got back, but that never happened," Robinson’s father said. Robinson’s family said the waves appeared high that day, but they did not see any beach warning flags when they arrived. A GoFundMe has been created to help Robinson’s family cover funeral expenses.
