A Gray man who crashed a car on Route 11 earlier this month, resulting in the death of a 4-year-old boy, has disappeared, according to the Cumberland County Sheriff’s Office.

On the morning of Aug. 11, Michael Minson, an unlicensed driver with a residence of 22 Whitney Road in Gray, lost control of a 1993 Honda Civic shortly after passing another vehicle on his way to work at Dunkin’ Donuts in Naples.

Passenger Crystal Petersen of Gray, who was likely the girlfriend of Minson, according to sheriff’s Capt. Don Goulet, was sent to Bridgton Hospital and then to Central Maine Medical Center in critical condition. Her 4-year-old son, Cameron Petersen, was ejected from the vehicle and declared dead at the scene.

The department is still investigating the crash, and no criminal charges have been filed, according to Goulet.

Minson moved into his mother’s Casco home immediately following the crash, Goulet said. Minson left his mother’s home on the night of Sept. 9 and has not yet returned, said Goulet, who declined to provide the name of Minson’s mother.

“She just knew that he was going out with some friends and she wasn’t overly concerned until the days turned to multiple days,” Goulet said. “She knew that the death of his girlfriend’s child was upsetting for him.”

Minson has now been listed on the National Crime Information Center’s list of missing persons. The department has opened a second investigation into Minson’s disappearance, Goulet said.

The accident occurred near Hancock Lumber’s Ryefield saw mill just before 6 a.m., and was the result, department officials said, of Minson speeding and losing control after passing another vehicle on his way to work at Dunkin’ Donuts in Naples. Details as to how fast the vehicle was traveling have not been released, due to the ongoing investigation.

While an accident reconstruction team from Windham police and the sheriff’s department is still working on the case, Sheriff Kevin Joyce said Minson was driving recklessly on a suspended license, and probably over-corrected after overtaking the car and then veered into an electrical pole, slicing the car in two. Joyce said the front half of the Honda was lying more than 10 feet from the back half, indicating the force with which the vehicle struck the pole.

Joyce said the reconstruction team has yet to determine if the boy was properly strapped into a booster seat that was found beside the vehicle, or whether the adults were wearing their seat belts. He said the seatbelt mechanism had been destroyed in the collision.
