"I think people are reaching out to say we're still with you, and this is what our thoughts are and that is comforting," said Julie Spahn Royal.
Despite the support, it's been a brew of chaos and unanswered questions for her and her family.
Her pregnant daughter Brittany Royal was found strangled by Big Island fisherman in May.
Brittany's boyfriend Boaz Johnson, named as police's primary suspect, has been missing ever since.
It was a case seemingly going cold, until a heated letter was sent to the news website the Big Island Chronicle, claiming two gruesome murders took place.
"When I first saw the letter I just sat in my car and cried," said Spahn Royal.
In recent weeks, posters have gone up not far from where Brittany's body was found saying: "Murders killed Bo! You killed the baby! They killed Bo on the lava flow! Confess."
Weeks earlier, someone sent the anonymous letter to the Chronicle, postmarked in Honolulu -- naming names.
The letter named two people as killers, and named others who knew of the attack, saying in part, "...the haole had to be killed," "...(they) took the two haloes for a boat ride at night, but they never came back."
It also included more gruesome details of the alleged murders, outlining everything from why the murders happened, to how and where.
"It certainly leads to a lot of speculation that's already been talked about," said Spahn Royal.
Big Island police said their case has not changed, with Bo still being their main suspect.
But as the rumors come and go, and the signs disappear, Spahn Royal said it is the unwavering support that gives her and her family strength.
"I had some lady from New York write me a private message on a card and sent me a sweater she had seen in a store that reminded her of the poncho that Brittany has in a lot of the pictures. It still brings tears to my eyes, that people that don't even know us or know her, care. That means a lot to us," she said.
Spahn Royal had planned to fly to the Big Island in November to do a network special on her daughter's murder, but she says the fear of being targeted changed her mind.
She said tips and support are still coming in regularly to their Facebook page "Justice for Brittany Jane Royal."
