A hacker targeted Minnesota state government databases in alleged retaliation for the acquittal of Officer Jeronimo Yanez in the fatal shooting of Philando Castile.
Cameron Crowley, 19, of Lino Lakes, was indicted on five federal charges on Tuesday, that includes intentional access and damage to a protected computer, and aggravated identity theft.
According to the U.S. Attorney's Office for Minnesota, Crowley "caused the transmission of programs, code, and commands to the protected computer servers, causing damages and a loss to the State of Minnesota of more than $5,000."
Going by the name of "Vigilance," Crowley is alleged to have breached state government databases in June 2017, as well as those belonging to two universities and a school district.

After the breaches, he would tweet from an account under his "Vigilance" name that featured the Joker as a profile picture.
One of these tweets said: "Where am I? Clock is ticking," while he claimed credit for a hack at MSU Moorhead that required faculty, staff and student online IDs to be reset.
In a statement he posted on his account, which is still live today, Vigilance wrote: "I have attacked large Minnesotan targets for one purpose: Retaliation for Ex-officer Yanez's acquittal.
"I will be back with other hacks. I will be back with other objectives."
Philando Castile was shot dead by Yanez during a traffic stop in St. Anthony in July 2016, with Yanez found not guilty of second degree manslaughter last year.
