Investigators are trying to identify a man who stayed at hostels under the alias, 'Ben Bilemy'

Investigators at a Florida Special Crimes Bureau Homicide Section have appealed for help to try and identify a mystery hiker found dead in the Big Cypress National Preserve.

The man - believed to be anywhere between 35 and 50 years old - was discovered lifeless in a tent at Noble's Campground on July 23 by passing hikers.

Police say he had hiked from New York to Southern Florida and believe the man may have family in New York area.

No forms of ID were found on the body or at the campsite.

While his real name has not been pin-pointed, Collier County Sheriff's Office said in a Facebook post Monday that he stayed at hostels in Virginia, Georgia and Florida using the alias 'Ben Bilemy'.

Also referred to as 'Denim' and 'Mostly Harmless', the hiker was found dead at Big Cypress National Preserve (pictured) on July 23 and is believed to have been dead for a few days

The notice states the 5ft 8in man also went by the nicknames 'Denim' and 'Mostly Harmless'. He weighed only 83lb when he passed away and is believed to have died within a few days of being found.

Investigators think he was living in the park and the unidentified man is noted as having teeth in 'excellent condition' and had grown a 'salt & pepper' color beard.

When he was discovered five miles north from the I-75 and 63 MM rest stop inside a yellow Brooks-Range Mountaineering 2-person tent (Foray model).

The deceased hiker was wearing a beige shirt, green shorts, and black Saloman hiking boots.

Despite the notice being posted by the homicide department, the Sheriff's Office maintain the death 'is not criminally suspicious'.

'With a low homicide rate in our safe community, our investigators also work all unattended deaths,' the Special Crimes Bureau said on social media.

As the search for his true identity continues, police have shared a composite to help connect them to someone who knows the man, as well as an image of a possible match. He has 'blue/gray eyes'.

'We know that many of our followers have suggestions and speculations about who he may be. We appreciate your thoughts and interest in this case,' the Facebook caption reads.

'At this time we are looking for his identity or information from those who knew him or know of his family. Our database connections will make appropriate matches on all of those persons that have been reported missing.

'Thank you.'
