When a teen saw a 67-year-old man walking alone in the woods, he likely thought that he had found an easy target. After donning a mask, he attempted to rob the stranger. Unfortunately for him, he’d pay a bitter price.

A case out of Upper Darby, Pennsylvania, involving an unnamed 67-year-old robbery victim and 18-year-old Tyler Williams of West Philadelphia, received national attention after the teen made a fatal mistake. After spotting the 67-year-old man walking a path in the woods at Cobbs Creek Park, Williams decided to confront him and demand cash, ABC 6 reported.

Williams had armed himself with a gun. There was one big problem, however. The teen had set out to make his intended victim believe his life was in danger, but the gun was actually a “toy,” according to NBC 10. Unfortunately for Williams, he succeeded in making the 67-year-old man believe his life was legitimately threatened.

After the masked assailant approached the older Pennsylvania man in broad daylight on that fateful Wednesday and pointed what later turned out to be a pellet gun in the man’s face, a brief physical altercation ensued. The intended victim grabbed the gunman’s firearm, deflecting it away from his head, as he simultaneously pulled out his own .38 caliber handgun.

Fearing for his life, the man shot Tyler Williams in the head, dropping him to the ground. The 67-year-old then exited the woods and called the police, who arrived only to realize the gun Williams had used in the attempted robbery was “fake.” But, even the police thought the pellet gun was “real” until they got a closer look at it, according to Upper Darby Police Superintendent Michael Chitwood.

Williams died at the scene. He was found with the pellet gun, a mask, and half a dozen cell phones on him. According to the Delco Times, the shooting was ruled “justifiable” after it was determined that the intended robbery victim was a “concealed weapons license” holder with no previous criminal record. Although he was initially taken to a local hospital with chest pains following the incident, he reportedly made a full recovery. With the shooting ruled an appropriate act of self-defense, he didn’t face any charges.

While most applaud the 67-year-old for doing what he felt need to be done at the time to ensure his own safety, there are those who condemn the fact that this man was able to defend his life with a firearm. They are seemingly troubled by the fact that a young adult with a “fake” gun is dead because an armed citizen was able to use lethal force to stop a crime from being committed against him. But, there are a few important things to point out here.
