"I see a guy in a big black jacket holding a knife about that size and he tells me basically turn the alarm off and give me money."
Johnson, keeping his wits about him, tells the man to follow him to the back bedroom where there may be some cash.
The suspect keeps the knife held tightly against Johnson as they walk through the house.
Johnson says he pretends to rifle through his drawer to get money but got his gun instead and fires a shot at the suspect.
The suspect takes off immediately. No word on if the suspect was hit.
