We're told Brian allegedly went to the store September 14
with an older woman and purchased the phone before they
left.
The timing is significant because Sept. 14 is the date
Laundrie's parents claim they last saw him leaving their
home. They say he had his backpack and was going to a
nearby nature reserve, but never returned. They reported
him missing Sept. 17.
11:44 AM PT -- According to the Laundries' family attorney, Steven Bertolino ... they did purchase a new phone, and he believes it's the one Brian left behind at home and the FBI is already in possession of it.
