Mary Smith's 52-year-old son, Ronald Smith, was helping his 94-year-old mom on her farm.

According to the police she was riding an all-terrain vehicle, ATV, when she accidentally ran over him. The Livingston County Sheriff's Department said he was pronounced dead at the scene.

The farm is located in Cohoctah Township about six mile north of the town of Howell.

Ronald Smith was opening a gate when his mother must have lost control of the ATV, a Kubota RTV 900 utility vehicle that she was riding. The vehicle hit the gate and it caromed off the gate and hit her son.

As Ronald was trapped underneath the vehicle Mary tried to get the vehicle off her son but was unable to do so. She was taken to a local hospital for treatment.

A horrible tragedy for the mom.
