The lawyer for Brian Laundrie’s family says the missing man’s parents are being “tortured” by protesters demonstrating outside their house, Insider reports.

The protesters have been appearing in front of Chris and Roberta Laundrie’s home in North Port, Florida, for weeks since their son, a person of interest in the murder of his fiancée, Gabby Petito, inexplicably vanished.

“They are being tortured in their own home by these protesters outside,” the lawyer, Steven Bertolino, told Insider.

The protesters are leaving signs on the Laundrie’s lawn, including images of Petito.

Last week, Chris Laundrie removed a sign that read “What if it was Cassie?,” an apparent reference to Cassie Laundrie, Chris and Roberta Laundrie’s daughter.

The woman who created that sign later sued Chris Laundrie alleging he stole the $40 sign.

Bertolini said the couple is being hounded and can’t live a normal life, such as “being followed when performing basic tasks like food shopping.”

“They are being harassed with lawsuits for a $40 sign that was more than likely on their property and should be considered litter,” Bertolino told the news website, adding, “And all of the foregoing is occurring when they have no idea whether their son is alive or not.”

The parents told police on September 17 that they had not seen Brian for several days, claiming that he told them he was going for a hike at a nearby nature preserve.

However, there has been no signs of Laundrie at the preserve despite an intense manhunt.

Authorities found Petito’s body September 19 in the Bridger-Teton National Forest in Wyoming. She died from strangulation and had been deceased for several weeks before being located, according to an autopsy.

Brian Laundrie is also wanted on charges of bank card fraud after he allegedly used Petito’s debit card after she died.

Laundrie’s parents are “hopeful” their son will be found, Bertolini told Insider.
