A 21-year-old inventor who disappeared after posting cryptic videos saying he was under attack is keeping a low profile, according to his mum.
Julian Brown has not been seen in public since July 9 after he posted a video claiming that he was under attack.
Nia Brown told reporters she could not provide anymore details.
But who is Julian Brown and why is there mystery over his whereabouts? We take a look below.
Who is Julian Brown?
Julian is an inventor who lives in Atlanta, Georgia, and has more than 1.7million followers on Instagram.
He gained prominence for his work in the energy field in particular ‘Plastoline’.
The inventor has gained lots of public attention and millions of followers after sharing updates on social media about his work.
He’s only hit the headlines this month after his mysterious disappearance from social media.
What did he invent?
Julian is the founder of Naturejab, a company that makes natural products, as ‘an innovator in the use of microwave pyrolysis of plastic waste.’
He is best known for inventing Plastoline – a device that he claims converts plastic waste into usable fuels such as gasoline, diesel and jet fuel.
This is achieved by microwave pyrolysis which heats plastic in the absence of oxygen to break it down chemically into fuel.
He first learnt his skills at school during a welding class.
Talking about his inspiration behind the creation of the technology, he said: ‘It made me so upset that even though we are told that we are recycling, plastic is clearly ending up in the oceans and landfills where it is affecting so many lives, including our own.’
He received $100,000 from Reddit co-creator Alexis Ohanian, to realise his dream.
Why has he gone missing?
Julian has not been heard from since July 9 and posted a chilling video before his disappearance.
He wrote in a post: ‘Something is happening, keep me in your prayers please. SCREEN RECORD THIS. I don’t know.
‘I’m certainly under attack… I can’t go into so much detail.’
Before July 9, he also posted some concerning messages where it appeared like he felt he was being targeted.
He wrote on July 3: ‘A SECRET Helicopter circled me in the middle of NOWHERE… and it gets even scarier – Pray for me please.’
It sparked concern from his followers that he was in danger for his invention.
His mum Nia told Daily Mail that Julian is not missing and that he is safe despite his quiet presence online.
She said: ‘I can confirm Julian is safe but in the best interest of his security I’m not able to provide any more information.’
But when she was pressed for further details, she said she could not provide anymore information.
It is still a mystery as to when Julian will make a public appearance again.
