According to sheriff's deputies, Walker started the morning with erratic behavior, even pouring a glass of water inside a cable box.
When his father tried to intervene, deputies said Walker punched him before grabbing a knife.
Walker is accused of going on a stabbing spree, attacking his sister, mother and an elderly relative inside the home on Pricewood Manor Court.
The family ran away from the knife-wielding suspect and called 911 from a neighbor's house.
