His parents initially told authorities that Laundrie said he was going hiking in the nearby Carlton Reserve on Sept. 14. According to the Laundrie family's attorney Steven Bertolino, that date was inaccurate.
"Upon further communication with the FBI and confirmation of the Mustang being at the Laundrie residence on Wednesday, Sept. 15, we now believe the day Brian left to hike in the preserve was Monday, Sept. 13," he told Fox News Tuesday.
