Holland residents Robert, 69, and Susan, 66, Kammeraad died in the June 1 crash.
Ferrysburg resident Andrea Molenkamp, 22, was the front seat passenger in the car that struck the motorcyclists late that Sunday afternoon.
She was the most seriously injured of the three women in the car that she said was driven by her friend, a 23-year-old Grand Haven woman.
A Freedom of Information request for the police report has been submitted to the Allegan County Sheriff’s Department.
Officials said the crash was still under investigation and denied access to the report.
A call to the detective bureau was also not returned.
The Grand Haven woman’s name was not revealed as she could face charges related to the crash.
Molenkamp said the women were on the way to a high school reunion at the time of the crash.
Police said the crash occurred when a vehicle driven by a 23-year-old Grand Haven-area woman was southbound on M-40. She failed to notice vehicles had stopped in front of her for a left turn.
The woman swerved into the northbound lane to avoid the vehicles and struck the motorcycle. The crash occurred about 5:40 p.m. on M-40 at Babylon Road in Allegan Township, according to other media reports.
Police said the motorcyclists wore helmets and the women in the car wore seatbelts.
All three women went to the hospital following the crash with non-life-threatening injuries, police said.
