Laundrie, whovanished around the same timeamid nationwide calls for his arrest, was found dead from aself-inflicted gunshot woundin the Florida wilderness last October.

In the notebook, Laundrie referred to Petito’s death as an “unexpected tragedy.”

He claimed Petito was injured as the couple crossed a stream in the dark. Laundrie claimed Petito had a “small bump on her forehead that eventually got larger” as well as other injuries, and that she was “begging for an end to her pain.”

Last week, a lawyer for the Petito family, Patrick Reilly, told PEOPLE that Laundrie’s assertion that the killing was merciful and stemmed from a “tragic accident” is “nonsense.”

“He is writing a letter as though he wants people to feel sorry for him,” Reilly said.

Petito’s family filed a civil suit against Laundrie’s family, alleging Christopher and Roberta Laundrie knew the whereabouts of Petito’s body during the time in which authorities were pouring resources into a massive missing persons investigation.

Petito’s parents, Schmidt and Joseph Petito, are seeking more than $30,000 in damages for the mental anguish they suffered due to the alleged deceit of the Laundries.

TheMarch filingalso alleges that Christopher and Roberta helped Laundrie conceal Petito’s murder and were making plans for him to flee the country.

The suit also alleges that instead of helping Joseph and Nichole locate their daughter, the Laundrie parents went on vacation with Brian and ignored pleas for help from Petito’s family — and that Roberta blocked Nichole’s phone number and Facebook profile in September to avoid contact as Nichole sought answers about what happened to Petito.
