Good Samaritan saves teens life with skills learned from ‘Shark Week’

Robert Nicholas shakes hands with Bailey Mcgroarty after the man helped save Mcgroarty, who was in a car accident.

Shark Week saves lives.

A good Samaritan who came across the scene of a horrific jeep accident in the town of Boston, New York, last week, used skills learned from watching the Discovery Channel to save a teenager from bleeding to death.

Robert Nicholas stopped to help Bailey Mcgroarty, 16, and three other teens in an overturned jeep. The teens had been on their way to a local fair when the driver veered off the paved portion of the road and lost control of the vehicle.

Mcgroarty suffered a severe arm laceration with arterial bleeding. The teen was in danger of bleeding to death.

"You don't even know if you're capable," Nicholas said of trying to help at the scene. "There was a lot of blood."

Fortunately for all involved, Nicholas have been watching TV that week.

"I've seen 'Shark Week,'" he told WGRZ. "I just got done watching, they showed how to do a tourniquet. That's where I learned. Quickly."

"And I did say that and they were laughing a little bit," he added.

Nicholas stayed with the teens until emergency crews arrived.

Mcgroarty was airlifted to Erie County Medical Center where doctors treated a broken wrist and a broken elbow, and replaced the artery in his arm with one of his veins.

Authorities believe Nicholas may have saved the teen's life — although Nicholas credits one of the other teens, 17-year-old Ryan Courteau, with initially applying a tourniquet.

"That other boy," a humble Nicholas told WGRZ, "he's the one. He never left him."

"I guess...he just felt like helping," said a tearful Mcgroarty. "I just want to say, I am grateful."

Nicholas doesn't consider himself a hero — and hopes that someone would do the same for his child.
