A Sandy Hook 'truther' entered a charity race in memory of one of the victims over the weekend, just to confront the woman's grieving family with hurtful and bizarre conspiracy theories.

Matthew Mills, 32, was arrested Saturday, after barraging victim Victoria Soto's younger sister at the Vicki Soto 5K run in Stratford, Connecticut.

Police say the Brooklyn, New York man yelled at the victim's family, saying the shooting was 'staged'. Mills himself claims he politely asked Jillian Soto, 27, a question, and that the situation has become overblown.

Truther: Matthew Mills, 32, was arrested on Saturday after crashing a charity race in memory of a Sandy Hook victim to confront her grieving family with a conspiracy theory about the mass shooting which killed 26

Vicki Soto was 27 years old in December 2012 when crazed gunman Adam Lanza invaded the Sandy Hook Elementary school and targeted her first-grade classroom. Soto has become a hero of the day in accounts from witnesses, who say she gave her life trying to keep Lanza from her classroom.

Tragically, Lanza killed her before she was able to save her entire class. Five of the 16 children in Soto's class were among the 26 people killed at Sandy Hook.

But Mills believes that this was all a hoax and he ran in Saturday's race for a chance to confront Soto's family with what he believes is the truth.

Victim: Victoria Soto has been considered a hero of the shooting for bravely giving her life in an attempt to save her first-grade pupils

Police say Mills ran up to Vicki Soto's younger sister Jillian and shoved a picture of Vicki in her face - yelling that not only did the shooting never happen but that Vicki herself never existed.

Jillian and another sister were reportedly left shaken from the incident.

In an interview with the New York Daily News, Mills contested the police account of events, saying that he signed up for the 5K to 'politely' ask Soto's family a question about whether a picture of Soto sitting on a rock at the beach had been photo-shopped.

'I went to the race to specifically talk to her, but I waited until the end, and I donated also,' Mills said. 'They’re making me out to be a bad guy. I just asked one question.'

The man who claims he is a 'journalist' says he was 'soft spoken' when he spoke with Jillian Soto at the race and didn't mean to offend anyone.

'I try not to speculate. There are shootings all the time with no conspiracies related to them. But this conspiracy about the photo has really caught on online. …People say the rocks don’t match up, the shadows don’t match up.'

Charges: Mills is due back in court on November 17 for a hearing. He faces charges of trespassing and breach of peace. On the right, Jillian Soto

After the confrontation, Mills ran from cops but was arrested soon after and booked on charges of trespassing and breach of peace.

He was released on $10,000 bail and is due back in court for his first hearing on November 17.

This isn't the first time Mills has gotten into trouble for his unorthodox beliefs.

Mills crashed a Super Bowl post-game press conference in 2014, and was arrested when he took the microphone away from Seattle Seahawks linebacker Malcolm Smith to spew his speculations about the 9/11 terrorist attacks.
