A family is grieving after a Lake Orion man died south of Au Train Island Sunday afternoon. 
 
 Police say the investigation is ongoing, but according to the victim's brother, the man died on a boating trip to pour his father's ashes into Lake Superior. 
 
 59-year-old Robert Louis from Lake Orion, Michigan died shortly after he and six other passengers fell out of their boat in Lake Superior near Au Train. 
 
 The group was on a 19foot wooden kit boat, and were out to honor the final wishes of Louis' father. 
 
 His father died just two weeks ago after years of battling Alzheimer's. 
 
 "My brother literally devoted his whole life to you know, stick around and making sure dad was taken care of for the last 4 years of his life and then two weeks later we had his ashes and his was half on mom's grave and the other half on Lake Superior," Robert Louis' brother John "Joe" Louis said. 
 
 Michigan State Police were dispatched to a boating accident Sunday afternoon around 6:00 p.m. 
 
 "When troopers arrived they found that six boaters had been rescued by a pontoon boat that had been in the area and were currently being treated for hypothermia. The seventh passenger was not recovered immediately," Michigan State Police Trooper Alan Park said. 
 
 A witness from shore told police he saw the boat take a sharp turn for reasons unknown at this time, spilling everyone on the boat into Lake Superior. 
 
 Police say the the throttle was still open when everyone fell out. 
 
 "What I gathered from the information was, he tried to grab the boat as it was circling around him or them and the prop hit him and I'm not sure if it made it so he couldn't swim or if it injured him bad enough to be life threatening," Alger County Sheriff's Department Officer A.J. Schirschmidt said. 
 
 The Alger County Sheriff's Department and U.S. Coast Guard searched the area for about 24 hours before the body was found. 
 
 "We searched for quite a while above water when the [helicopter] was around," Schirschmidt said. "The Coast Guard got some better information of kind of where they figured the accident occurred so at that time we put two divers in the water." 
 
 Robert Louis' body was found by the Alger County Sheriff's Department Monday afternoon around 3:00 p.m. south of AuTrain Island. 
 
 "Just everybody he met was his friend, he was very helpful, kind," Joe Louis said. "The kind of guy that would run into a building on fire to help the people, just, incredible."

 MUNISING, MI - Police have identified the body of a Michigan man found in Lake Superior after a large wave washed seven people off a kit-made wooden boat in a weekend accident. 
 
 The victim is Robert Louis, 59, of Lake Orion, Michigan State Police said Tuesday. 
 
 The rescue and recovery effort took place near Pictured Rocks National Lakeshore. 
 
 Police initially said all those swept overboard in Sunday's accident near Autrain Island had been on a pontoon boat. On Tuesday, police corrected that information, saying were aboard a 19-foot wooden boat that had been constructed from a kit. 
 
 The boat's owner, Tim Preston of Marquette, Louis, and five others were on board near the island's south side when a large wave hit the boat, pushing everyone overboard. 
 
 Louis attempted to swim back to the boat, but drowned, police said. Authorities searched on Sunday and Monday before the Alger County dive team recovered his body Monday afternoon near the accident site. 
 
 The other six boat passengers were rescued Sunday by a group on a pontoon boat that had been in the area. They were treated for hypothermia.
– A family tragedy was compounded this week in Michigan when the body of a 59-year-old man was found Monday, a day after he fell out of a boat while scattering his father's ashes on Lake Superior. WLUC reports Robert Louis' father died two weeks ago after a battle with Alzheimer's. "My brother literally devoted his whole life to ... making sure Dad was taken care of for the last four years of his life," Louis' brother, John Louis, says. On Sunday, Robert Louis and six others were on a boat on Lake Superior to scatter his father's ashes. "He had told us that he was happy to go up and spread his ashes and follow his final wishes," one of Louis' neighbors tells WJBK. It's unclear exactly what happened out on the water—MLive reports the boat was hit by a wave, but a witness tells WLUC the boat made a sudden sharp turn—but all seven aboard fell in. By the time troopers arrived, a pontoon boat had pulled six people from the water and they were being treated for hypothermia. Louis was nowhere to be found. His body was discovered following a search nearly 24 hours later. A sheriff's department officer says it appears Louis had tried to grab the boat but was hit by the propeller. Now his family is left to mourn again. John Louis says his brother was "the kind of guy that would run into a building on fire to help." A benefit concert is being held Friday in his memory at the American Legion in Lake Orion where he would often play the guitar. (A New York man honored his childhood friend ... by flushing his ashes.)
