James Fairbanks was charged Thursday with first-degree murder and use of a deadly weapon to commit a felony. Prosecutors believe 43-year-old James Fairbanks killed Mattieo Condoluci, a convicted sex offender. "The State of Nebraska hereby complains to the court that James Fairbanks is alleged to have violated the following laws of the State of Nebraska:...On or about 14 May 2020, in Douglas County, Nebraska, James Fairbanks did then and there purposely and with deliberate and premeditated malice kill Mattieo Condoluci," a complaint read. Condoluci's death comes as no surprise to his own daughter, Amanda Henry."He's hurt so many people, and it's a matter of time before somebody did it," she said.Investigators believe Fairbanks sent a confession email to KETV Newswatch 7. The email, sent to KETV NewsWatch 7, from sender "Stop Predators," said "I killed Matteio Condoluci Thursday May 14th."The anonymous sender said he or she had been looking for an apartment in the area when he discovered Condoluci on the Nebraska Sex Offender Registry. The sender described Condoluci as standing in his driveway pretending to wash his truck while staring at a group of children playing in the street."Having had my own experience with these type of predators I knw (sic) the damage he would do to those kids," wrote the emailer."I've worked with kids for years who have been victimized and I couldnt (sic) in good conscience allow him to do it to anyone else while I had the means to stop him".The emailer also wrote "I know in this messed up judicial system that means I will face far more severe punishment for stopping him then (sic) he did for raping KIDS."Condoluci was convicted in Sarpy County 13 years ago of sexual assault of a child. "I've been through so much hurt and pain. There are many times I wanted to do it myself but I didn't want to give up my freedom, my family," Henry said.Fairbanks' defense requested a $500,000 bond, arguing he is not a threat and doesn't have a criminal record. However, a judge determined no bond would be set. Still, Steve Lefler said his client is still "surprisingly upbeat.""Normally people, our citizens hate people who have been accused of first-degree murder. This is what makes this a kind of unusual case," said Fairbanks' attorney.Lefler said inmates are giving Fairbanks standing ovations, supporters are sending him money to his jail account and signing petitions to free him, including Condoluci's daughter."He has tapped into the vein of righteousness that the city of Omaha has," Lefler said.Chief Deputy Douglas County attorney Brenda Beadle insists pre-meditated murder will not go unpunished."I've said it before and I'll say it again. It's never a good idea to take justice into your own hands. Vigilante justice isn't the answer," Beadle said.Fairbanks is a paraprofessional with Omaha Public Schools's alternative middle school program. The district said he's on leave.
