A Texas family claims a religious cult have drugged their son and turned him against them.

Jordan Reichenberger, 27, had gone to preach in downtown Austin on Halloween night in 2016, when he disappeared.

His family were distraught, initially believing he may have been car jacked. But when they were eventually able to contact their son, he told them he'd left the city with some elder members of the controversial Church of Wells. He was currently at the church's compound in East Texas.

When they reached him, however, he told them: 'I don't think it's my time to leave yet.'

He also texted friends and family saying: 'Do not fear for me my friend. I have decided to follow Jesus and forsake all; please forgive any pain or grief I have caused you.'

Reichenberger was at the compound for five days before his brother, father, and several friends drove out to the Wells compound to take him home, KVUE reports.

After hearing horror stories of other families struggling to get their children back, Jordan's brother, Ian, said they approached the situation carefully.

'When families show up angry like 'hey give us our person back, give us our kid back', the cult would be like 'oh look how angry your family is.' So, that's why we went with friendship, love' he said.

Eventually, after several hours of heated discussion with the church elders, Reichenberger was allowed to leave.

But when he returned home, his mother Kim says she noticed he wasn't himself.

'At one point, his eyes rolled back in his head and we're just like 'what is going on here?',' she said.

Drug tests later revealed that he had sleeping pills and muscle relaxers in his system after returning from the compound.

Reichenberger admits that the felt 'just kind of like a haze' while he was at the church compound.

He explained that while he would never take drugs or tranquilizers voluntarily, all his food and drink during the five days at the compound were provided by the church.

'Abhorrent. It's a real shame that people can be doing that kind of stuff in the name of God,' said Reichenberger.

He and his family have since contacted the police about the results of the drug test.

The family said when they first realized that he was missing, they asked police to trace his cellphone.

They found it had last 'pinged' outside of the city of Dime Box, Texas, an hour outside of Austin.

His family also began reviewing surveillance footage from businesses around downtown Austin, where Reichenberger had been preaching, and found him talking to a man in plaid and another guy, at around 2.47am, before he walks off with the man in plaid.

The family also recovered another video of the unnamed man in plaid preaching to a man in a clown costume that same evening. When they contacted the Heidi Search Foundation in San Antonio, they were told that the interaction sounded like their son had met with someone from the Church of Wells.

It was only days later Reichenberger finally got back in touch with his family who were frantically trying to reach him.

On the night that Reichenberger went missing, surveillance footage showed a member of the church (in the plaid shirt) appearing to confront a man dressed as a clown. Reichenberger's family were horrified when reviewing the footage, they saw the same man talking to their son

While Reichenberger was allowed to leave the compound, to the surprise of many, another family are still waiting to be reunited with their daughter.

Andy and Patty Grove's daughter, Catherine, joined Church of Wells nearly six years ago and the parents haven't heard from her in over a year.

They are terrified about what might have happened to her.

'We have information from law enforcement that she had made numerous escape attempts,' Andy Grove said.

Her mother believes that Catherine was also drugged when she was first brought into the church.

'I honestly believe that my daughter was drugged at the beginning and there's some reason why she decided to escape four times and she's asked to go to a women's shelter twice,' said Patty in tears as KVUE asked where things stand with Catherine.
