Police in Austin, Texas say a man’s life was saved due to the courageous actions of a United States Air Force Reservist.

Lieutenant Brandon Teel.

Never underestimate the power of a Good Samaritan.

Or, a bystander who just so happens to be a military service member — carrying a concealed weapon.

That’s what went down Monday night when 47-year-old Darren Terry was found by officers with three lacerations. They suspect his brother, 30-year-old Chris Terry, to be the one who stabbed him.

Teel cops say, saw what went on and took care of the situation the only way he knew how — then reported it.

This from KATV:

When he realized the severity of the fight, police say Teel took out his concealed weapon, for which he has a valid permit, and held the suspect until Austin officers were able to take him into custody.

Teel, 35, of Ward, is an active-duty United States Air Force Reserves 189th Airlift Wing and is stationed at the Little Rock Air Force base.

The Austin police chief says Teel’s actions saved a life.

“Lt. Teel is a perfect example of a responsible concealed carry permit holder,” said Chief Bill Duerson. “He acted heroically in the face of extreme danger and avoided a tragedy.”

The younger Terry was charged with first-degree domestic battery, and is being held on a $10,000 bond at the Lonoke County jail.
