A Florida school board agreed to pay $200,000 to three different families of students who died after they were hypnotized by their high school principal.

Following a year-long case, the school board at the Sarasota County School District reached on Tuesday a $600,000 settlement after former North Port High School Principal George Kenney admittedly hypnotized two teenagers who committed suicide and another one who got into a fatal car crash, the Herald-Tribune reports.

One of the victims was 16-year-old Wesley McKinley, who was placed under hypnosis by Kenny a day before he killed himself in April 2011. Brittany Palumbo, 17, also committed suicide in 2011, about five months after being hypnotized, while Marcus Freeman, 16, died in a car accident in 2011 after using a self-hypnosis technique that Kennedy taught him.

"The School Board has concluded that a mutually acceptable settlement is in the best interests of all parties involved," Scott Ferguson, a spokesman for Sarasota County Schools, said in a statement to NBC News.

A subsequent investigation found that Kenney hypnotized up to 75 students, staff members and other people from 2006 to 2011 without a license.  After pleading no contest to practicing therapeutic hypnosis without a state license, Kennedy resigned in June 2012.

A lengthy independent investigative report also found that he admitted to ignoring at least three warnings to stop the sessions.

"I'm not saying I used great judgment all the time here," he said, according to the report. "I think I used poor judgment several times."

"There's nothing that can bring Marcus back, but the Freemans hope this will give them some closure," said Marcus' mother, Dana Freeman, who called Kenney "a rogue principal" in statements Wednesday to the Sarasota Herald-Tribune.

According to attorney Damian Mallard, who respresents the victims' families, the parents filed for a lawsuit in order to hold the Sarasota County School District accountable.

"It's something they will never get over. It's probably the worst loss that can happen to a parent is to lose a child, especially needlessly because you had someone who decided to perform medical services on kids without a license," Mallard said. "He altered the underdeveloped brains of teenagers, and they all ended up dead because of it."
