When police pulled John Cramsey over on the way into New York, they found a huge collection of powerful weapons.

The 50-year-old was arrested and sparked claims that cops had foiled a deadly attack on the Big Apple.

But the Second Amendment supporter insists that he is not a vigilante or a terrorist.

Instead he claims he is just a heartbroken father who was trying to help a girl at risk of being dragged into a heroin addiction - four months after his model daughter overdosed with her boyfriend.

In an interview with The New York Post from the Hudson County Correctional facility in New Jersey, he revealed how he suffered after his 20-year-old daughter Alexandria 'Lexii' Cramsey passed away.

'My last memory is giving my daughter a hug in the rain,' Cramsey said.

She was found dead alongside boyfriend Marquillis 'Quillis' Calhoun, 22, in his Allentown, Pennsylvania, warehouse apartment In February.

They had both suffered fatal overdoses while watching Netflix

Ever since he says he has been trying to rescue girls heading down the same path.

But it was his determination that led to a bungled rescue mission which ended outside the Holland Tunnel on June 21.

The owner of a Pennsylvania gun range was stopped in a SUV heading into the Big Apple with friends Dean Smith and Kimberly Arendt beside him.

Cramsey was arrested, and is now facing a slew of gun charges. He has tried to have his bail reduced, but the judge has failed every time.

He has since claimed that he was on his way to Queens to try and 'extract' a 16-year-old girl from a party.

The teenager woke up in a hotel next to Sierra Schmitt, 20, who fatally overdosed on heroin.

It has been part of his crusade since his daughter Lexii's death.

'My world ended,' he told The Post.

Lexii adored her Calhoun, and even gushed on Facebook about how he would treat her like a princess, but Cramsey didn't like him.

'If I had a chance to go back, I would've intervened,' he said. 'I didn't spend enough time with [Lexii], but there was no way anyone could have spent enough time with her.'

Five months before her death, Calhoun even reached out to Cramsey on Facebook, assuring him nothing would happen to her.

At the time she was building a career in modelling.

She had been invited to Mexico for a three-month residency after stints working professional in Philadelphia and Atlanta.

But she struggled with substance abuse after getting hooked on Xanax that had been prescribed by her doctor.

Her ex-boyfriend Anthony Aniades, 24, told The Post she would eat it 'like candy' every day.

Cramsey said: 'I knew she was doing Xanax and Percocet. To prescribe Percocets to a child at a very young age is totally stupid. It was early in her teens, 12 or 13.'

A few days before Lexii died, she wrote in her diary that she was worried about Calhoun.

Gina, her mother, shared extracts with The Post.

It read: 'I'm worried about Quillis. I think he's secretly doing heroin again, and I don't know how to help him.'

Lexii's death left her father desperate to fight for the lives of heroin addicts.

He said: 'Words can't describe how fast it happened,' he said. 'She went from this beautiful young lady to this beautiful young woman overnight, and just as fast, she was gone.'

He created a Facebook group, Enough is Enough, to provide 'grief counseling and solutions' to Pennsylvania families coping with addiction.

'There was nothing I could do to bring my baby girl back. The only thing I could do to heal myself was to help other parents who are going through the same heartache,' he told The Post. 'The difference is not seeing the body counts go up.'

He claims that since her death, he has rescued dozens of addicts.

'There are people I've literally carried out on my shoulder,' he said. 'I've also had people who consciously went into treatment.'

'I'm not the criminal people say I am,' Cramsey said. 'There is a lot people don't know yet.'
