A good Samaritan pulled the two drowning men from the waters at Indiana Dunes National Park, according to the Indiana Department of Natural Resources. They were then transported to a nearby hospital, where they were declared deceased.

The Porter County Coroner identified the individuals as 65-year-old David Meneou from Joliet, Illinois, and 20-year-old Jameson Meneou from Lockport, Illinois. The IDNR confirmed that they were father and son.

David’s brother told ABC7 that his nephew Jameson lived with autism. He also said that David was a loving father who dedicated his life to his son.

“Preliminary investigation reveals both were in the water when Jameson Meneou went into deep water and began to struggle,” a news release from the IDNR read in part. “David Meneou attempted to rescue his son but also began to struggle in the deep water.”

No further information was immediately available as authorities continue to investigate.
