Brian Laundrie's sister says she does not know where he is, and 'I'd turn him in'

The sister of Brian Laundrie has doubled down on her assertion she has no idea where he is, as authorities search for him after the death of his fiancée Gabby Petito.

“No, I do not know where Brian is. … I’d turn him in,” Cassie Laundrie said in an exclusive interview with ABC’s “Good Morning America” which aired Tuesday.

Cassie Laundrie said if she could talk to her brother, she would tell him to come forward.

“I worry about him. I hope he’s OK, and then I am angry and don’t know what to think. … I would tell my brother to just come forward and get us out of this horrible mess,” she said.

Petito was found dead September 19 in a national forest in Wyoming, 18 days after authorities say Brian Laundrie returned to his parents’ Florida home without her following a cross-country trip the pair took this summer.

After Petito’s family reported her missing September 11, Laundrie left the Florida home September 14 and hasn’t been seen since, his parents told authorities.

Though authorities have not explicitly connected Laundrie to Petito’s death, they are looking for him, in part over a federal arrest warrant accusing him of illegally using another person’s debit card.

A coroner made an initial ruling last month that Petito’s death was a homicide.

Sister says she last saw her brother September 6 on camping trip

Cassie Laundrie said the last time she saw her brother was during a family camping trip at Florida’s Fort De Soto Park in early September — days before Petito’s family reported her missing. The trip happened September 6-8, and the site is about 75 miles from where Brian Laundrie’s parents live, county officials have said.

Cassie Laundrie told ABC she last saw and spoke to him September 6.

“We just went for a couple of hours and we ate dinner and had s’mores around the campfire and left. There was nothing peculiar about it. There was no feeling of grand goodbye. There was no nothing,” Cassie said of her last encounter with her brother, later adding she was “frustrated” she didn’t pick up on anything.

She shared photos of her brother with her 5-year-old son, she says were taken that day.

“It was just a regular visit,” she told ABC.

Brian Laundrie’s parents told investigators they last saw him leaving their North Port, Florida, home on September 14 with a backpack, and told them he said he was going to the nearby 25,000-acre Carlton Reserve, according to police.

Police reported they were given that information September 17, three days after he allegedly left. Investigators have since spent days searching for Laundrie at the Carlton Reserve outside Venice, Florida.

The day Cassie Laundrie learned of her brother’s disappearance, she informed authorities of the September 6 camping trip, she told ABC.

“It was not hidden from law enforcement. … I’ve been cooperating with the police since day one. I have been in touch with law enforcement,” she said.

She said she has also tried to get in touch with her brother, but the “phone went to voicemail.”

In late September, Brian Laundrie’s parents released a statement through their attorney saying “Chris and Roberta Laundrie do not know where Brian is,” and were “concerned about Brian and hope the FBI can locate him.”
