Jeff Otto is the last one of three surviving arsonists to plead guilty in the June 14, 2009 torching of the Young Champions of America headquarters in Phoenix.
​The third member of a group of karate instructors who burned down the Young Champions of America headquarters last June, killing a fourth arsonist in the process, has pleaded guilty in the case.

Jeffrey Otto, 20, entered a guilty plea last week to charges of manslaughter and arson of an occupied structure. His friend and fellow Young Champions karate instructor, Josh Robinson, 28, died in the fire.

New Times covered this tragic saga of betrayal in our January 21 edition.

Otto was the last holdout of the three surviving arsonists to plead guilty. Court records show he'll be sentenced May 11.

Moniza Murillo, 20, was the first to 'fess up to the crime, and had agreed to testify against Otto if need be. Her own sentencing date has yet to be scheduled.

It's unclear whether those two will receive any less time than the possible ringleader in the crime, 20-year-old Jonathan Antonucci, who had embezzled thousands of dollars from Young Champions and had started a rival karate instruction company.

Antonucci was sentenced last month to 14 years in prison by Maricopa Superior Court Judge Joseph Kreamer. The term was less than the 21-year maximum that victims and prosecutor Jon Wendell had called for, but it was higher than the typical sentence for the crimes.

Kreamer told Antonucci during the sentencing that he found it "disturbing" how kids who took karate classes from the arsonist had to later learn of the deadly crime.

Phoenix Fire Department investigator Marika McCue told New Times for our January article that Murillo and Otto apparently had nothing to gain from the crime, and simply joined in on the plan our of peer pressure.

He couldn't of been that great of a person. All of the people involved. Didn't think about the consequences. They didn't think about the firemen responding putting there lives on the line. They are responsible for the death of there co defendant. Sensei or not. They lit a fire and someone died. They are lucky they don't get life.


The sensei that died, was my instructor for 6 years... So i suggest you watch what comes out of your mouth. He was an amazing man, and you dont know anything about the situation or him. ...even 2 years later...this event still hurts me.

Jeffo Otto, greatest guy I ever knew. Got pulled into a crime that went wrong. He made me the man I am today, he was also the most charitable person. We both went down town, many times, to feed and give clothes to the homeless.
