The censure states that Hernandez would afterwards ask a victims for some-more bare or intimately pithy images or videos, or he would send what he has to their friends and family. 

The FBI contacted Facebook, requesting annals associated to a “Brian Kil” account.

Facebook responded with an email residence and IP for a registration. The IP residence went to an unknown proxy, that is a pull between a person’s mechanism and a internet. People can use unknown proxies to censor their information when online.

Investigators trust Hernandez also used a Tor network to censor his communication. Tor program bounces a user’s information around a world, around opposite computers run by other users.

“There’s zero bootleg about a Tor network or a dim web,” U.S. Attorney Josh Minkler said. “There’s zero bootleg about people wanting internet privacy. we totally know that and honour that. All of us do. We honour a constitution. But it does make it formidable when somebody does that.”

  • Brian Kil
  • Brian Kimore
  • Brianna.lik
  • Plainfield Massacre
  • Brianna Kilian
  • Brian Mil
  • Bre Harris
  • Lamarr Raymer
  • Ryan Kel
  • Greg Martain

TIMELINE | Brian Kil threats investigation

For a FBI, a mangle in a box came in Jun 2017, when a decider certified a use of a Network Investigative Technique, or NIT, to find a suspect’s loyal IP address. 

A NIT is a tiny square of formula that can be trustworthy to a video or photo. When somebody opens a video or photo, a NIT discloses a user’s IP residence to a FBI. A NIT, as Minkler said, is a bit like a pathogen when it’s trustworthy to a file. 

A NIT is a argumentative apparatus used by FBI. In 2015, it was used to hack 8,700 computers with one aver as partial of a child publishing investigation. 

The NIT was placed on a square of media that was sent to Brian Kil by one of a victims he was extorting. When he non-stop a media, law coercion was means to brand his genuine IP address. 

Once investigators had a suspect’s IP address, they subpoenaed Bright House for subscriber information on a location, that came behind to a residence on Eucalyptus Drive in Bakersfield, Calif. 

According to a military news from a Kern County Sheriff’s Office in California, Hernandez lived during a residence with his partner and her grandmother.

A few days later, a FBI requested a use of “pen-trap devices,” a form of wiretapping to and from a IP address. A decider postulated a request.

“As you’ve seen, we’ve followed a 4 corners of a law,” Minkler said. “We did not personally get somebody’s internet. We did not personally take anybody’s emails. We went by a decider on all we did or by a grand jury to do this box a right approach so it will mount adult in court.”

One of a online communications intercepted by a FBI showed that somebody during a IP residence noticed a print “Brian Kil” posted when he threatened Plainfield schools in 2015.

The FBI also commissioned a stick camera nearby a house, that showed a male relating a outline of Buster Hernandez come in and out of a house. A examination of a Tor annals showed a Tor was accessed usually when Hernandez’s partner was not during a house, and usually when Hernandez was during a house.
