Deadly Lake St. Clair boat crash: What we've learned about investigation so far

The Macomb County Sheriff’s Office has released additional details about a fatal Lake St. Clair crash that killed three people. The incident occurred around 8 p.m. on Oct. 7 near MacRay Harbor in Harrison Township. A 911 call was received at about 10:48 p.m. after a passenger, a 58-year-old woman from Chesterfield Township, swam to shore and told investigators the boat— a Formula Thunderbird—had capsized. Authorities said the crash happened between two vessels: a black 1981 23-foot Formula Thunderbird and a white 1991 28-foot Sea Ray Sundancer. Deputies recovered the three victims from the overturned boat around 5 a.m. Thursday; all were pronounced dead at the scene. Investigators later brought a person in for questioning, but it was released pending further review, with navigation data and video analysis ongoing.
