In an eight-page letter, Brian Laundrie said, "I ended her life."
The attorney for Brian Laundrie's family has released images of a notebook where Laundrie confessed to killing fiancée Gabby Petito.
In an eight-page letter, Laundrie said, "I ended her life."
He claimed 22-year-old Petito, a Long Island native, was injured while on a hike and he wanted to take away her pain.
The notebook was discovered in a Florida swamp near Laundrie's body last October where he took his own life.
A month earlier, Petito's body was found.
