A mother in Michigan allegedly drove to a cemetery and set a car on fire with her bound 11-year-old son inside, authorities say.

The unidentified woman, 48, remains held at the Monroe County Jail on attempted murder and arson charges. She was expected to be arraigned sometime Wednesday, Det. Sgt. Jeff Pauli of the Monroe County Sheriff’s Office told The Post.

Authorities said they received a call early Tuesday from a 50-year-old man in Frenchtown Township who reported his wife was may have harmed their 11-year-old son. Acting on a tip, deputies later found a 2014 Ford Focus on fire at the Roselawn Memorial Park in LaSalle, but the woman and her son were not inside the vehicle.

Deputies found the pair talking to staff at a different location inside the cemetery as firefighters put out the blaze inside the car.

Investigators say it appears the woman started a fire inside the car’s trunk after binding the boy’s wrists and locking the doors.

“The mother later attempted to ignite a fire using gasoline inside the passenger compartment where the boy sat,” the sheriff’s office said in a news release. “This fire did not ignite while the boy struggled to free himself from the vehicle.”

The mother then freed the boy from the car and walked away, ultimately finding an employee at the cemetery who took off the boy’s bindings.

A possible motive for the incident is still being investigated.

The boy, who was also not identified, was taken to a hospital for precautionary measures before being released.
