A 47-year-old Petersburg man died last Saturday night after an unrestrained dog ran into the roadway in Monroe County's Summerfield Township, forcing his motorcycle into a residential mailbox. Lance Dusseau was riding westbound on Ida West Road, west of Summerfield Road, alongside a 19-year-old relative around 9:20 p.m. when the dog darted out from the south shoulder.
According to ClickOnDetroit, the dog first struck the left-side saddlebag of the younger rider's motorcycle before being forced directly into Dusseau's path. The impact caused Dusseau to lose control, and his bike came to rest after striking a mailbox on the southbound side of the road. He was pronounced dead at the scene.
The 19-year-old relative brought his motorcycle to a controlled stop on the south shoulder and was not injured. Per the same report, that rider was wearing a helmet at the time of the crash, while Dusseau, according to the sheriff's office, was not. Investigators have said alcohol was not a factor in the collision.
Helmet Choice Was Legal Under State Law
Michigan does not require all adult motorcyclists to wear helmets. The state repealed its universal helmet mandate in April 2012, and under Michigan Vehicle Code MCL 257.658, riders 21 and older can legally forgo head protection if they've held a motorcycle endorsement for at least two years or completed an approved safety course, and carry at least $20,000 in first-party medical benefits coverage.
Statewide, the stakes of that choice are stark. Motorcycles made up just 1.1% of all Michigan traffic crashes in 2024, yet motorcyclists accounted for 15.1% of all traffic fatalities that year, with a death rate of 22.4 per 100 million vehicle miles traveled compared to 1.1 overall, according to Michigan Traffic Crash Facts. Of the 152 motorcycle drivers killed that year whose helmet use was documented, 63 were unhelmeted, while 89 helmeted riders also died.
A Deadly County for Riders
Monroe County has emerged as something of a regional hotspot for fatal motorcycle wrecks, recording 10 such deaths in 2023 — a toll that placed it alongside Genesee and Kent counties even though larger metro counties like Wayne and Oakland saw higher overall totals, per Sommers Schwartz. The county has seen fatal motorcycle investigations before; in June, a 66-year-old Trenton man died in Frenchtown Township after a minivan turned into his path at Telegraph and Newport roads, a case the sheriff's office also investigated, as reported by WTOL.
Animal strikes present a distinct danger to riders on two wheels. Research from the Insurance Institute for Highway Safety notes that unexpected animal encounters pose extreme loss-of-control and swerving hazards for motorcyclists, often leading to rider ejection on impact — a hazard Hoodline has previously reported on animal-related roadway dangers.
Dog's Owner Remains Unidentified
Police have not shared information about the dog's status following the collision, nor have they said why the animal was unrestrained at the time. Under Michigan's 1919 Dog Law, codified at MCL 287.262, owners must keep their pets leashed whenever off private property, and Monroe County's local animal control ordinance similarly requires any dog removed from private property to be secured by a leash or control device no longer than six feet, held by a capable handler.
Failing to restrain a dog under those statutes can serve as prima facie evidence of negligence in a personal injury or wrongful death suit, per Michigan precedent set in *Zeni v. Anderson*, according to the Lee Steinberg Law Firm. Plaintiffs would still need to show the statutory violation caused the harm, but the framework leaves open the possibility of civil liability once the dog's owner is identified.
Reconstruction Team Continues Investigation
The Monroe County Sheriff's Office maintains a specialized Traffic Crash Reconstruction Team within its Traffic Services Division that uses 3D forensic mapping technology and specialized software to process fatal and high-level injury crash sites — the same unit now working the Ida West Road case. The incident remains under investigation, and deputies have not disclosed why the dog was in the roadway or whether an owner has been located.
The sheriff's office is asking anyone with information to contact Lieutenant Brian Quinn or Deputy Sheriffs Alec Preadmore and Steven Warren of the Traffic Services Division at 734-240-7541.
