Protesters are begging the fiancé of missing Gabby Petito to break his silence on her whereabouts as they descended on his home.

The group arrived at Brian Laundrie's home in Florida on golf carts and chanted "Where's Gabby?" as questions over the missing influencer's disappearance mount.

Gabby has not been seen since she left a hotel with Mr Laundrie in Salt Lake City, Utah, on August 24.

She had been writing and posting on a social media blog as she travelled around the United States with Mr Laundrie - before he returned home on September 1 without her.

Gabby's family have pleaded for answers, as police named Mr Laundrie as a person of interest in the case.

Mr Laundrie has now also disappeared himself, his lawyer confirmed on Friday.

He was last seen by his family Tuesday morning.

On Thursday, protesters drove a golf cart outside the house where he had been staying with his parents.

Placards on the vehicle read: "Where is Gabby", "Bring Gabby Home", "Speak up!" and "North Port Loves Gabby".

A protester said: "This is a horrible tragedy. For whatever reasons this guy wants to lock himself in this house and not participate in finding this beautiful young lady.

"It's heartbreaking, it's sad, it's disrespectful, horrible, it's everything.

"I do not know how the mom and dad could sit in that house and support their son and not, well, at least say this is the last time we've seen Gabby, or this is where Brian left Gabby. We need information. Gabby needs to be found.

"Can you imagine, your daughter is dating some guy, they go on a road trip and that's it. That's how you lose your daughter.

"That's how you never see your daughter again. Because she went on a road trip with the wrong person."

Another said: "We feel like we should be doing something. It is heartbreaking. I have three little girls, if this was my daughter I would go crazy."

Gabby's dad made an emotional appeal on Thursday as he asked for help to get his daughter back.

During the interview with HLN, Joe Petito said his gut tells him "something bad has happened."

He said: "I am never, I'm never going to be able to hold my baby girl again.

"But my head tells me, that if I focus on that, I'm not going to be able to do that job that needs to be done. That her fiancé should be doing. He should be leading this charge, and he's not.

"The goal is to bring Gabby home safe. I am asking for help from everyone here. I am asking for help from the parents of Brian, and I am asking for help from the family members and friends of the Laundrie family as well."

Brian's sister Cassie Laundrie broke the family's silence in an interview with ABC News where she described Gabby as a sister to her.

She said she had not been able to get in contact with her brother.

Bodyworn footage from police in an incident 13 days before Gabby's disappearance has been released. It shows an emotional Gabby telling officers she was "trying to get him to stop telling me to calm down" and said they "have been fighting all morning."

She said the couple were stressed because of the YouTube blog they were working on.

Laundrie was seen with scratches on his face and arm, which he tells an officer were due to Gabby trying to get keys from him, and hitting him with her phone.

When an officer asked her if her boyfriend had hit her, she replied, "I guess" and made a grabbing motion on her chin.

Laundrie said he had "pushed" her during the altercation and police determined she was the primary aggressor and they separated the couple for the night.

On Friday, Laundrie's lawyer said the FBI had removed items from the Laundrie family home to help in the search for him.
