MACOMB COUNTY, Mich. - A boat crash in Lake St. Clair Wednesday night left three people dead.

The crash happened at around 8 p.m. on Oct. 7 near MacRay Harbor in Harrison Township.

Here's what we know:

The Macomb County Sheriff's Office says its dispatch received a 911 call about the crash around 10:48 p.m. on Oct. 7, after a passenger aboard the vessel, a 58-year-old woman from Chesterfield Township, swam to shore. The passenger told investigators the crash happened around 8 p.m. and that the boat, a Formula Thunderbird, had capsized.

Marine Division deputies and the MCSO Underwater Search and Rescue Team searched the area overnight and recovered three people from the submerged vessel around 5 a.m. on Thursday. All three were pronounced dead at the scene.

On Thursday afternoon, the Macomb County Sheriff's Office identified the three killed in the boat crash as Craig Miller, 52, of Macomb Township; Heidi Baldwin, 56, of St. Clair Shores; and Gerald Grzadzinski, 64, of Chesterfield Township.

The 58-year-old Chesterfield Township woman who swam ashore was taken to a local hospital, and she is expected to be okay.

The sheriff's office said the crash happened between two boats: a black 1981 23-foot Formula Thunderbird and a white 1991 28-foot Sea Ray Sundancer.

The Sea Ray driver, a 40-year-old Roseville man, is cooperating with investigators. A 36-year-old Roseville woman, a second adult woman and a child were also aboard the Sea Ray.

Aerial footage from Sky 4 shows the Formula Thunderbird being towed and reveals significant damage to the starboard side of the stern.
