New England Patriots player Julian Edelman was in Texas visiting a friend when he got a disturbing message on social media. So he took immediate action.

“I can’t help but notice in the comments section there is a kid saying he’s going to shoot up a school, can everybody alert the authorities please????” an unidentified Instagram user posted under a photo of Edelman in Austin.

In addition to the message under his photo, the Instagram user sent him a separate direct message. “Dude, there is a kid in your comment section says he s going to shoot up a school, i think you should alert the authority,” the message said.

Edelman told The New York Times that when he saw the message, his first thought was the high school massacre in Parkland, Florida.

Edelman alerted Shannen Moen, his Boston-based assistant, and asked her to scour through the hundreds of comments under his latest post at the time — a picture of him with fellow NFL player Danny Amendola on March 25.

Moen found the alarming comment. “I’m going to shoot my school up watch the news,” the unidentified Instagram user wrote, according to The Times.

Boston Police Commissioner William B. Evans said Moen alerted them and his detectives traced the commenter’s IP address to Port Huron, Michigan. Life saver and solid receiver. 

Julian Edelman is a game changer, on and off the field. He’s a real life superhero, and clearly lives by the old adage, you see something, say something. Great work Julian!
