Brian Laundrie's sister said police bodycam footage looked 'typical' of how he and Gabby Petito fought

• Brian Laundrie's sister said that the police bodycam footage showing him and Gabby Petito in seemed "typical" of how they fought.
• "Whenever they fight they would take a little break and come back and be fine," Cassie Laundrie told ABC News' "Good Morning America."
• "All I want is for her to come home safe and sound," the sister said of Petito, who is missing.

Brian Laundrie's sister said that police bodycam footage released by Utah authorities showing Laundrie and now-missing fiancée Gabby Petito in the aftermath of a scuffle seemed "typical" of how the couple fought.

"It looked typical of both of them," Cassie Laundrie told ABC News' "Good Morning America." "Whenever they fight they would take a little break and come back and be fine because that's what you do in a couple."

Officers with Utah's Moab Police Department responded to an incident involving Petito and Laundrie on August 12 near Arches National Park while the couple was in the midst of a cross-country road trip.

In the bodycam footage, Petito appeared visibly distraught as the couple told police that they had gotten in an argument, resulting in Petito slapping Laundrie.

According to body-camera footage, officers considered charging Petito with domestic violence in the incident, despite Laundrie saying he wasn't hurt and that he didn't want to press charges. Instead, police recommended the two spend the night apart.

Nearly one month later, Petito was reported missing to New York police by her family. The 22-year-old was reported missing on September 11, 10 days after Laundrie returned home to Florida with the van they were traveling in and without Petito.

Laundrie, who police have named a "person of interest" in Petito's disappearance, has since refused to speak to authorities or publicly and has hired an attorney.

"Obviously, me and my family want Gabby to be found safe, she's like a sister and my children love her," Cassie Laundrie said in the interview. "All I want is for her to come home safe and sound and for this to just be a big misunderstanding."

The sister said that she hasn't been able to speak to her brother.

"I wish I could talk to him," she said. "I've cooperated with every way that I can. I wish I had information that I could give more. This is all that I have."

Cassie Laundrie described her brother as a "wonderful uncle."

"He's always been there when I need him," she said. "He's been there every time Gabby has needed him."
