Harris County investigators are looking into a deadly shooting involving an off-duty deputy.
Authorities say two men got into a fight inside a restaurant on the North Freeway and Richey.
The two took the fight to the parking lot. One man grabbed a gun while the other grabbed a knife. The man with the knife then began stabbing the other guy.
An off-duty deputy ran over, telling the man to drop the knife. He refused, so the deputy shot him.
The man who was stabbed is in critical condition.
