The father of a man accused of killing 10 people at a Colorado supermarket testified at his murder trial, shedding light on his son's mental state leading up to the tragic event.
Before the 2021 attack in Boulder, the father recalled instances where his son exhibited concerning behavior. He mentioned waking up to his son claiming there was a man in his room, only to find no one there. The father also noted his son talking to himself and breaking a car key fob out of fear it was being used to track him.
