Brian Laundrie's parents revealed they were mistaken about when their son left for his 'hike'

The Laundrie's family attorney revealed that they mistakenly gave the wrong information to the FBI about their son's escape while police were searching for his fiancée's body in Wyoming.

According to Brian Entin from News Nation, who has been following the story closely, lawyer Steve Bertolino released a statement saying that Laundrie left the house for his "hike" on Monday, Sept. 13, not Tues. Sept 14, as was previously stated.

"The Laundries were basing the date Brian left on their recollection of certain events. Upon further communication with the FBI and confirmation of the Mustang being at the Laundrie residence on Wednesday September 15, we now believe the day Brian left to hike in the preserve was Monday September 13."

The statement comes less than 24 hours after Laundrie's sister came forward saying that she isn't sure if her parents are involved in his disappearance. TMZ reported Monday that Cassie Laundrie spoke to protesters outside her home saying that she doesn't know where he is and that she too wants answers.

"Cassie saw her brother Brian on Sept 1 when he stopped by her home and again on Sept 6 at Fort De Soto Park. Law enforcement agencies are well aware of these dates," Bertolino said. He also claimed, "any prior communication by Cassie that does not reflect these dates is simply a difference of relating an answer to a question misinterpreted by Cassie or poorly posed by the inquirer."

Cassie, however, says that the lawyer told her parents to stop talking to anyone, even her. She said that her parents hadn't contacted her since.

Gabby Petito disappeared last month and was later found dead in Wyoming. Laundrie drove back to his parents and then disappeared "hiking" and hasn't been seen since.
