30-year-old Maria Witham is charged with elevated aggravated assault.
Officials say a Knox County sheriff’s deputy was called a home on the Robert Cemetery Road at around 12:30 Monday morning.
There was a report of a domestic assault that resulted in the stabbing.
Authorities aren’t saying much about what happened, but they say Witham was armed with a knife when they arrived, and that she surrendered without incident.
Her 8-year-old son and 28-year-old Joshua Anthony were both transported to the hospital aboard a ferry.
They were both treated and released.
Investigators are trying to determine a motive for the alleged attack.
