Boston: New England Patriots receiver Julian Edelman was in Texas visiting his former teammate Danny Amendola late last month when he received a direct message on his Instagram account: "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."

Edelman instantly thought of the mass shooting about five weeks earlier in Parkland, Florida, in which 17 people were killed. "With the emotions of what happened, and I have a kid now, I said, holy Toledo, what is going on?" Edelman said in an interview this week.

He quickly notified his assistant in Boston, Shannen Moen, who looked through the hundreds of comments that followed Edelman's most recent post on Instagram. She found the alarming message: "I'm going to shoot my school up watch the news."

Moen called emergency services, and a police officer soon arrived. The officer saw the screen shot, then called her chief, who sent two detectives to Moen's house. The detectives collected some information about the person who posted the threat.

They then returned to their office, where they made an emergency records request for account information, which allowed them to determine the sender's email and IP address, which was traced to Port Huron, Michigan.
