Members of Anonymous attend the rally on Tuesday.Diana Reese for Al Jazeera America
Members of Anonymous made an appearance as well: At least six people wearing the group's signature Guy Fawkes masks stood on the fringes of the crowd.
"We're here because Daisy didn't get the justice she deserved," one Anonymous member said.
He said the group's involvement in the Maryville case is not an attack on any specific person, or on the town of Maryville.
"We're not trying to attack the whole town," he said. "We stand for justice."
Yet the presence of Anonymous has stirred up many residents.
"I'm afraid," said one woman, a lifelong resident of the town.
Daisy and her mother, Melinda Coleman, had announced earlier that they would not attend the demonstration out of concern for their safety, but in a Facebook message on the Justice for Daisy page, Melinda stressed that she does not think Maryville is a terrible town and that the family had been "happy there" until her daughter was attacked.
Melinda's father, Chuck Moeller, attended the rally.
"I saw how much it tore them apart," Moeller said of the alleged rape, with tears in his eyes. "I just want to see justice."
Not everyone there was in support of the Colemans, though. Pete Hayse, the husband of Dr. Sally Hayse, who owns SouthPaws Veterinary Clinic in Maryville, said his wife has received death threats since Melinda Coleman told the Star that she was fired by Sally after the alleged rape. Melinda blamed her termination on people in the town turning against the family.
"Melinda worked five and a half hours total" before she was fired after working at the clinic, Pete Hayse said. And that was, he said, before the alleged rape even occurred.
Others talked about the harassing phone calls to local government offices and to a restaurant where Matthew Barnett had once worked, along with the mob mentality that some say has been characteristic of comments about the case on social media.
Former County Commissioner Joe Baumli hopes Baker's appointment to the case will help the town heal by bringing the chance for "either vindication or for justice."
