Fox News obtained the notebook in which Laundrie admitted killing Ms Petito, which revealed he perversely claimed the killing was “merciful”.
“I ended her life," Laundrie wrote in a notebook recovered by the FBI from the Myakkahatchee Creek Environmental Park alongside Laundrie’s body on 20 October 2021.
“I thought it was merciful, that it is what she wanted, but I see now all the mistakes I made. I panicked. I was in shock. But from the moment I decided I took away her pain, I knew I couldn't go on without her.”
A coroner ruled Ms Petito died by manual strangulation. Her body was found on the border of the Grand Teton National Park in Wyoming on 19 September after a month-long, nationwide, missing persons enquiry.
He also wrote: “From the moment I decided, took away her pain, I knew I couldn’t go on without her.”
