Bennie Price told WMC-TV that her daughter, 32-year-old Toni Price went to Riverview Elementary School in Memphis intending to confront the parents of another child who had been in a spitting match with her child the previous day.
According to court records, an employee reported a drunk woman armed with a sword was running through the halls of the school and had threatened to cut her.
Officers who arrived on the scene retrieved a black cane that concealed the blade.
Bennie Price said her daughter would never have hurt anyone at the school.
Toni Price is charged with aggravated assault and having a weapon on school property.
