A spokesperson for a white nationalist organization is claiming that Nikolas Cruz was among the group's members.

Jordan Jereb said in multiple interviews on Thursday that the 19-year-old shooter who killed 17 people in his Valentine's Day massacre was a member of Republic of Florida.

Among the many aims of that group is to make Florida its own white-ethno state.

Jereb said that the group did not have any involvement in the shooting at Marjory Stoneman Douglas High School, or encourage actions of that kind among members.

There is still no definitive proof however of this claim, leading some to comment that it it nothing more than a ploy to capitalize on a national tragedy.

And a spokesman for the Leon County Sheriff's Office in Tallahassee where ROF is based said the office has 'very solid' information on the group and 'there's no known ties that we have that we can connect' Cruz with the group.

Jereb claimed that Cruz, who was adopted as a baby, was brought up in the organization by another member.

The teenager reportedly carpooled to at least two training exercises held by the group, which is only a few years old at this time.

At those exercises it is believed he participated in the group's paramilitary activities.

It is unclear when Cruz first developed an interest in the 'neo-Confederate and anti-gun control militia group.'

Cruz also told at least two classmates he was involved with the group.

Thew Anti-Defamation League was the first to report on Cruz's involvement with the organization, reaching out to the ROF to see if they could confirm he shooter was a member.

It was Jereb who fielded that call and told the ADL about Cruz's involvement.

On Wednesday, Cruz walked into his former school almost one year after he was expelled and opened fire with an AR-15, killing 17 people before he hid among those fleeing the scene and got himself away from the area.

He was captured an hour later after police reviewed surveillance video that was taken at the school.

It was revealed on Wednesday evening that the FBI had been alerted to an alarming comment made by Cruz back in September but never investigated the young man.

That is because the agency was unable to determine the identity of the person who posted that comment on YouTube under the username 'Nikolas Cruz.'

Students who knew Cruz have also been speaking out, including one young man who wrote: 'Nick attacked one of my friends once. He brought shotgun shells to school and made many threats against others. He had an insta full of pictures of dead animals that he killed.'

The teen, who wrote that his parents had prohibited him from giving interviews, added: 'Mental illness needs to be recognized or things like this happen. People i know are f***ing dead.'

Cruz has not be attending Marjory Stoneman Douglas High School at the time of the massacre, having been expelled for disciplinary reasons during the 2016-17 school year.

It was at least the third time that Cruz had been forced to leave a learning institution, and came at a particularly difficult time in his life.

Cruz, who has a younger brother Zachary, lost his mother Lynda back in November as a result of complications from the flu.

The 68-year-old mother-of-two developed a case of pneumonia shortly after checking herself in to receive treatment for the seasonal sickness.

On Instagram, Cruz could be seen holding firearms, ammunition and the semiautomatic AR-15 rifle he likely used in bthe attack.

That weapon was legally obtained and the family's lawyer Jim ledws

One photo shows several guns, including rifles with scopes, laying on a bed. Another appears to show a frog that had been killed.

His father Roger died of a heart attack back in 2005, just a few years after he and wife Lynda adopted Nikolas and his brother Zachary.
