Brian Laundrie sleuths speculate ‘black box’ was sealed in dry bag found before his remains – and some think it’s a GUN

ONLINE sleuths have a new theory that a mysterious "black box" at the bottom of Brian Laundrie's dry bag could be a "gun."

On a Facebook group dedicated to the Gabby Petito case, users speculated about a close up picture of the dry bag recovered by Laundrie's father Chris Laundrie near where the body was fond.

The picture appears to show a long object at the bottom of the bag that users claimed looks like a "black box."

"I'm really curious about what the black box is and what, if anything it has inside..." the post read.

'SO DISTURBING'

Meanwhile, a veteran investigator criticized police for their handling of the Brian Laundrie case after Chris Laundrie found the dry bag within minutes of joining the search.

Chris and his wife Roberta Laundrie arrived at the Myakkahatchee Creek Environmental Park to help investigators search the area around where Brian's remains were found on Wednesday.

In less than 90 minutes after their arrival, Laundrie came across the bag.

Tom Joyce, a retired Lieutenant Commander with the NYPD, told The Sun that the search was a "s**tshow," adding that he found it "so disturbing" Laundrie had come upon the bag so easily.

He said that police allowing Laundrie to go "walking off by himself during such a high stakes investigation is beyond me."
