Three Killed in Lake St. Clair Boat Collision, Probe Underway

Overview

• The crash occurred on Wednesday night, Oct. 7, near MacRay Harbor when a 23-foot Formula Thunderbird capsized after colliding with a 28-foot Sea Ray Sundancer.
• Three people recovered from the overturned Formula were pronounced dead and identified as Craig Miller, 52; Heidi Baldwin, 56; and Gerald Grzadzinski, 64, while a 58-year-old woman who swam ashore was hospitalized and is expected to recover.
• The Macomb County Sheriff’s Office said investigators brought one person in for questioning and later released them pending further investigation and potential referral to the Macomb County Prosecutor.
• Detectives are analyzing speed and navigation data, reviewing video, examining onboard equipment and using underwater search-and-rescue work to recreate the sequence of events, a process officials say is technically complex.
• Commanders urged the public to avoid unverified online speculation and cautioned that evidence collection and forensic analysis could take weeks before any charging decision is made.
