FBI and police find 'articles' belonging to Brian Laundrie in 25,000-acre ...

Articles belonging to wanted fugitive Brian Laundrie were found in Florida's Myakkahatchee Creek Environmental Park early Wednesday morning.

Laundrie family lawyer, Steven Bertolino, confirmed the discovery to DailyMail.com and claims officers are now conducting a thorough search of park for the missing 23-year-old. 

Photographs shared by Fox News show his parents, Chris and Roberta Laundrie, joined by law enforcement, along a trail.

Chris and Roberta alerted investigators on Tuesday night that they intended to search for Laundrie on Wednesday and authorities agreed to meet them at the reserve. 

'After a brief search off a trail that Brian frequented some articles belonging to Brian were found,' Bertolino said. 'As of now law enforcement is conducting a more thorough investigation of that area.'

The FBI and North Port Police Department have closed the 25,000-acre park, which just reopened to the public on Tuesday after being closed to the public for nearly a month due to the ongoing search for Laundrie. 

Federal investigators issued an arrest warrant for Laundrie for 'use of unauthorized access device' last month after alleging he used a Capitol One Bank debit card that wasn't his. He is also the sole person of interest in the homicide of his fiancée, Gabby Petito.

The FBI's discovery comes just one day after internet sleuths claimed they had proof that wanted Laundrie was still alive.

Minnesota-based blogger Shaynah Dodge, who has been closely monitoring the investigation into Gabby Petito's homicide, claims Laundrie's Pinterest account has followed a new account in the past three weeks.

Laundrie has been on the run from police since fleeing his parents' Florida home more than a month ago, after he returned from a vacation with his girlfriend Gabby Petito, alone. Petito's body was later discovered. She was murdered by strangulation.  

'Three weeks ago I posted in my stories about Brian's Pinterest account. In my screengrab from three weeks ago he followed 145 people,' Dodge posted to her Instagram stories. 

'Tonight I was scrolling some of his pins on his account and I noticed this … He now follows 146 people. That's weird right?' 

Similarly, Twitter user Ian Scott claimed Monday morning that Laundrie's email account was active last Friday.

'When I first discovered #BrianLaundrie's email account, I posted that there was activity using it on September 18th,' he wrote. 'Now the Latest Update is showing activity for October 15th!'

The alleged discoveries come about a week after police said there was no evidence suggesting if Laundrie - who disappeared over a month ago - was dead or not. 

Dodge presented her more than 77,000 followers with the alleged evidence on Monday night, 7News reported.

She posted a screenshot of what she believes to Laundrie's Pinterest account that was reportedly taken three weeks ago. The account followed 145 users.

In another post, she shared a grab she claims to have taken Monday that shows his alleged account following 146 users.

'Like of course his follow count went up as people have flocked to his pages but how did who he follows go up within the past three weeks?' she asked her followers.

'Can bot pages make you follow them?' 

She continued: 'Someone could have had a private page and changed their settings? Not sure, but seriously, I cannot stand this guy on the run. I'm so fed up with this. Everything in this case feels so cryptic.'

The blogger also argued that she knew the account belonged to Laundrie because it had shared boards with Petito and his mother. 

When questioned about Dodge's allegations, Pinterest told DailyMail.com: 'We don't share details related to accounts.'

Dodge's allegations followed those of Scott who, earlier that day, claimed that Laundrie had been using the internet. 

Although he did not present his followers with evidence, Scott argued that someone had accessed Laundrie's Gmail account.

'Either he's active, or his account has being hacked, or feds are checking the account,' he tweeted.

Scott also explained that he is using an open source intelligence tool called EPIEOS to monitor Laundrie's digital activity. 

'Just to clear something up that some may not understand regarding #BrianLaundrie's Gmail. The tool being used to observe his digital activity, is EPIEOS. The tool enables us to see what apps/services Laundrie has linked to them,' he wrote.

'So to be clear, we're not talking about him accessing his email account, to check emails. Simply that there's some activity linked to apps or services linked to that Gmail address. Each time that happens, there's a time stamp and date.'

Scott argued that he first saw activity tied to Laundrie's accounts on September 18 at 1am. He claims there was activity again on October 16 at 4.56pm.

'The FBI can also see this,' he said. 'If they're looking.'

The self-proclaimed intelligence expert also claimed to have uncovered - with the help of podcaster Michael Collins - a phone number belonging to Laundrie.

'This morning (October 19th) I got a message from @2thecurve. He's found parts of another telephone number belonging #BrianLaundrie,' Scott tweeted Tuesday.

'This could help in closing in on his *potential* location. I'm digging in to find the missing parts. The number may link directly to Laundrie, or even to one of his allies.'

Scott reported that Laundrie has a new mobile number, registered with an area code beginning in 9, and is using an Alcatel cellphone. 

'The number is connected to a PayPal account,' he alleged. 'However I will not publish public information here. The purpose of what we're doing is trying to establish that there is a digital footprint, which takes many forms.'

Authorities have not confirmed the validity of either sleuth's claims.

Likewise, Google - owner of Gmail - did not immediately respond to DailyMail.com's request for comment. 

Laundrie, who is the sole person of interest in Petito's homicide, was reported missing by his parents on September 17 after claiming they last saw him three days prior. His whereabouts have been unknown ever since. 

Investigators and TV personalities like Duane Chapman - known as Dog the Bounty Hunter - and longtime 'America's Most Wanted' host John Walsh have been searching for the fugitive.

There have been no signs of Laundrie, 23, at the Carlton Reserve in Florida, the area his parents cite as the last place he was seen.

Last week, North Port police noted there was 'nothing to suggest' whether Laundrie was dead or alive.

Officials claimed no one had seen him in the reserve and search teams didn't find any physical evidence of his presence in the area. 

Investigators have chased down leads in multiple states since Laundrie was last seen in September, but to date there has not been a confirmed sighting of him.
