Brian Laundrie's parents are defending their actions during the publicized search of Gabby Petito and their son late last year.

Chris and Roberta Laundrie filed a motion for dismissal last week after Petito's parents, Joe Petito and Nichole Schmidt, had filed a civil lawsuit against them on March 10, which include several allegations that weren't previously mentioned during the FBI's publicized search and investigation into the couple's deaths, WFLA reports.

“The Laundries’ decision to exercise their constructional rights to silence, privacy, and counsel, and to have their attorney speak for them under such trying circumstances and media pressure, could not be further from conduct that is extreme or goes beyond all bounds of decency,” motion to dismiss states via WFLA. “It is what most people would and should do in such a situation.”

Additionally, the motion also states that “there are no more facts that could emerge that would bolster the plaintiff’s claim.”

The documents initially filed by the Petito family claim that Gabby Petito, 22, died at the hands of Laundrie, 23, on August 27 during their cross-country road trip, which coincides with the coroner's office determining Petito died by manual strangulation, but also claims she suffered blunt force injuries to the head and back.

Petito's parents' lawsuit claims Laundrie told his parents about the incident "on or about" August 28, which was nearly two full months before his remains were found in his home state of Florida.

“While Joseph Petito and Nichole Schmidt were desperately searching for information concerning their daughter, Christopher Laundrie and Roberta Laundrie were keeping the whereabouts of Brian Laundrie secret, and it is believed were making arrangements for him to leave the country," the lawsuit alleged via WFLA.

The Laundrie family is also accused of acting “with malice or great indifference to the rights of” to Petito's family in the lawsuit.

“Christopher and Roberta Laundrie exhibited extreme and outrageous conduct which constitutes behavior, under the circumstances, which goes beyond all possible bounds of decency and is regarded as shocking, atrocious, and utterly intolerable in a civilized community,” the lawsuit states via WFLA.

Petito and Schmidt are seeking damages of at least $100,000 and accuse the Laundries of causing pain and mental anguish as a result of "willfulness and maliciousness" in relation to the case.

On October 12, Teton County Coroner Dr. Brent Blue -- who performed an autopsy on Petito -- announced her death was ruled as a death by strangulation and the manner of death to be a homicide during a press conference.

Laundrie, the lone person of interest in connection to Petito's disappearance and death, was discovered weeks later at the Carlton Reserve campsite near his family's Florida home and confirmed to have died of a self-inflicted gunshot wound, his family's attorney, Steve Bertolino, confirmed to TMZ.

Dr. Blue said Petito's death is believed to have occurred 3-4 weeks prior to her remains being found on September 19 and confirmed to match her days later.

Dr. Blue confirmed the ruling was made while working alongside local and federal authorities. No other information will be released in adherence with state law.

Laundrie was the center of a publicized search by the Federal Bureau of Investigation and local authorities at the Carlton Reserve prior to his remains being discovered.

Dr. Blue said local law enforcement would decide who would be charged in connection to Petito's homicide case.

On September 30, police released additional bodycam footage which showed Petito telling an officer that an argument with Laundrie got physical.

The newer footage stems from the incident on August 12 in Moab, Utah in which police made contact with Petito and Laundrie after a bystander called the Moab Police Department and reported seeing a man hitting a woman.
