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.
For the first time, the parents of Brian Laundrie, the fiancé of Gabby Petito, have released writings from his personal notebook.
A Florida judge will decide Wednesday whether Petito's parents have enough evidence to pursue legal action and send the case to a jury.
Gabby Petito's parents allege during the search for the young woman, Brian Laundrie's parents knew their son had killed her.
