"You in pain is killing me," Petito writes. "I'm not trying to be negative but I'm frustrated there's not more I can do."
The family of Gabby Petito settled their wrongful death lawsuit against Brian Laundrie's estate for $3 million.
Petito "displayed the classic hallmarks of an abused partner," the notice of claim says, by taking blame for the incident. The officers "did not press further," the notice says.
Newly revealed footage shows Gabby Petito shopping with Brian Laundrie at a Whole Food in Wyoming just before her murder.
Her father posted a message on Twitter, writing that she "has inspired so many to live, travel and leave unhealthy relationships."
Petito's parents claim the Laundries made statements despite knowing Gabby was no longer alive, knowing where her body was located and knowing that her parents were "frantically looking for her," according to an amended complaint.
