A Texas teenager has pleaded guilty to swatting and to making earlier threats to a Minnesota high school, according to court filings submitted last week. He formally pleaded guilty on August 7 to one federal count of making threats to kill

The case marks a rare occasion when a person has been caught "swatting," orchestrating a fake 911 call that results in a massive show of force by a local police force against an unsuspecting target.

Between October 2014 and May 2015, 19-year-old Zachary Lee Morgenstern pulled off numerous swatting incidents in the Marshall, Minnesota, area. He also threatened a police officer and her family and threatened to detonate a bomb at a high school, among other allegations. It's unclear why he chose to target another town approximately 1,000 miles away from his home in a Houston suburb. However, court filings show that Morgenstern had an associate in Marshall who was interviewed by the FBI.

In April 2015, after months of harassing Marshall Public Schools officials and pulling off swatting attacks in the area, Morgenstern called a public resources officer assigned to Marshall High School and left a voicemail saying that it was “not possible” for him to be caught. Why? Well, he was a “hacker,” and as everyone knows, “you can’t catch a hacker.”

He continued his eloquent rant: “You’re a fat fucking lesbian. I want to kill your family, I want to kill your family, I want to make you watch me kill your family. I am going to call a bomb threat into your house every day, just to piss you off. And then, I am going to jerk off to it. How does that make you feel? How does it make you feel to know that I am a hacker??”

So how did federal authorities ultimately bring down Morgenstern?

Well, among several of the handles and e-mail addresses that the 19-year-old used was anonymously.lulzsec@gmail.com and the Twitter handle @RIURichHomie. The FBI simply filed a subpoena to Google for the records associated with that account and another to Twitter. They both showed that they had been accessed by the same IP address from a Comcast account served to a home in Cypress, Texas.

Authorities also found through a simple Google search that Morgenstern had previously controlled the Twitter account @ZackL337H4X0R.

The teen was interviewed by the FBI in Houston in 2012 related to a DDOS attack in his previous school in Tomball, Texas.

Earlier this year, two teens from the United States and Canada were arrested on similar charges.

Morgenstern could face a maximum penalty of 10 years in prison.
