Authorities went to the home after a neighbor called a sheriff's dispatcher to say McVay's son had come to her home and said he had just shot his mother.
McVay's body was transported to the Stark County Coroner's office for an autopsy. The sheriff said McVay's 15-year-old daughter is currently staying with relatives. It is unclear whether she witnessed the shooting.
The 10-year-old boy is being held in Richland County Juvenile Detention and will appear in court Monday afternoon. A woman who answered the phone at McVay's home said she had no comment and hung up.
Authorities are investigating what may have caused the shooting.
